@IsabelSafar It's dumb but I've used this strategy for every test I've ever taken. Substitute the unknown word with a nonsense word, and you can get a good idea of how the word is being used, if not it's definition.
For example, I might reread the stimulus as:
"The mild winter also allowed many species to stay in their summer range all winter without migrating south, thereby limiting the usual waffles accompanying migration. Hence, last year's mild winter is responsible for this year's larger-than-usual bird population."
Waffles must be bad. Its implied that if there are waffles accompanying migration, there's less birds at the end of the migration.
Ugh I'm soo confused, could someone please explain to me what our objective is when dealing with Causal Mechanism and Causal Chains for both Strengthen and Weaken questions?
Up until now I have understood the Phenomenon hypothesis and the Ideal experiment framework, but I feel that this section does a poor job of effectively explaining what our objectives should be for Causal Mechanisms and Causal Chains; I seriously do not even understand how we are supposed to approach these. The "You Try's" for the Causal Mechanism's(AKA lesson 5) don't seem consistent enough for me to least at least derive a central theme, and then we have this???
@Mari_on_nette So, I got it wrong but after studying it here is what I unbderstood: In the stimulus they mentioned two things mild winter caused
Birds don't go to feeders
Birds didn't migrate
The text also explains how birds not migrating affected the population of birds but it never explained how the feeders affected the population so whenever you see that they're giving you two observations to reach a conclusion, the answer is usually how one of them contributed to the result.
So, for this type of question, when the question stem says "strengthen the reasoning of the argument," we are looking for the answer that strengthens the premise??
So for questions like this, are we looking at both premises, seeing which premise out of all has no causal mechanism, and finding a strengthening reasoning for that specific premise?
Dude, this made no sense. C litterally sounds just like an alternative hypothesis and disproves the first premise.
If the 1st premise is saying "mild winters increased forage, which decreased vistis to the feeders" then C claims that "no, the reason they don't come to feeders is becasue of predetors".
Qeustion at hand: How do you strengthen a causal argument that contains multiple causal premises but only one clearly supports the conclusion?
Explanation: Identify a causal premise that is currently irrelevant, then add a link that connects it to the conclusion. A Strengthen answer can work by completing a causal chain:
If A → B is given, and the conclusion depends on C, strengthen by showing B → C.
🧠 Core LSAT Rule (memorize this)
If a premise doesn’t yet affect the conclusion, strengthen by giving it causal relevance.
Answer C provides a link that makes the first premise of the argument relevant to the conclusion: The Mild winter let birds forage in the forest instead of at the bird feeders where they are suseptible to pray and could be killed by predators, so since they are not exposed to predators and are foraging in the forest where they are less likely to do due to the mild winter, the argument is strengthened that the mild winter is responsible for this year's larger-than-usual bird population.
@SMRegalado Reasonable assumptions that don't contradict the "truth" of the answer choice. If the prompt says "if true" then it doesn't matter if the choice says "Mars is made up of moonbeams," we can't assume that it is incorrect just because in the real world it IS incorrect.
Conclusion: Last year’s mild winter reason for larger bird population.
Why: it was mild for bird to forage naturally and not visit feeders; they stayed home in summer range without migrating south.
Assumption: it's a strengthening question - we know that mild winter made it easier for birds to forage naturally... but what makes it so that foraging naturally (versus eating at feeders) is ALSO/ADDITIONALLY beneficial (other than the fact that the winter was mild)?
---> Answer choice C: eating at feeders = more dangerous because of predators; foraging naturally = easier because of the winter (milder makes it easier), but ALSO because it's safer (less vulnerable to predators).
Took me a while to figure out that I'm looking for a misssing premise rather than affriming the conclusion. atleast that what makes the mose sense to me in this case.
Not that i am not gaining a ton out of these classes - but does anyone else sometimes skip or pause the videos early if you find the explanation is over explaning or like causing you to overthink the solution?
Causal relationship questions require more work for me than all others. I hate them. Other types, I can read it, and work it all out in my head. Anyone feel the same way?
the questions we've been examining in this section were more directed towards finding an alternative hypothesis by strengthening/weakening the connection between the phenomenon and the conclusion. This question to me was distinctly different because it directly strengthened a weak phenomena that seemed non-essential, which strengthened the entire argument.
A critique about the explanations is its very obvious they know the answer and why its wrong, so the explanation just feels like 'think this way' rather than actually TEACHING. Its getting annoying lol
I wasn't understanding how C could be correct and then I reread the prompt, "Birds eating..." I had been reading the prompt as "Birds who eat at feeders..." and was like how does this apply to anything we are talking about birds at large not just feeder eating birds.
you could play with it and make up your own answer choice to weaken it by attacking the support. i think D would be the closest thing to weakening it that the answer choice gives.
I understand how this can be seen as strengthening the reasoning, but wouldn't this also be adding an alternative hypothesis instead of enforcing the original conclusion.
@maxiheinz2003405 No, because it's not an alternative hypothesis, it's a secondary causal mechanism pointing to the same conclusion/hypothesis. The conclusion of the stimmy states that the mild winter caused the larger-than-usual bird population this year. One reason that the conclusion is likely to be true is that the birds didn't need to migrate, which has some level of attrition associated with it. Another supporting factor is that the birds could forage naturally and didn't need to risk eating at bird feeders, which is more dangerous according to answer choice C. Both of these support the primary conclusion of the stimmy, which is the mild winter led to conditions that caused the bird population to grow. Giving a second reason for why the conclusion is true is a great way to support it.
To weaken the argument, an alternative hypothesis gives an alternate explanation that points away from the conclusion in the stimmy. For example, an alternative hypothesis that would weaken this argument would be something like:
Due to increased funding for animal control in the area, populations of feral house cats, one of the primary threats to local bird populations, have been severely reduced this year.
This would offer an alternative hypothesis for why the bird population has grown this year unrelated to the mild winter, thus weakening the argument in the stimmy.
In Answer choice - C why are we considering that predators could affect the feeders. The stimulus doesnt even mention any predators. Please help me out.
Answer choice C says that birds eating at feeders are more vulnerable to predators THAN are birds foraging naturally.
IF--as the stimulus suggests--the mild winter led more birds to forage naturally instead of relying on feeders, THEN fewer birds were exposed to the higher risk of predation associated with feeders. That means fewer birds would have been killed by predators this year compared to a typical winter (AKA, there is a larger-than-usual bird population this year).
I like to use hypothetical numbers sometimes to help me understand things more clearly. So, imagine that in a normal year, 1,000 birds feed at feeders, and 50% fall prey to predators—so 500 die. But this year, with the mild winter, maybe only 100 birds use feeders, resulting in just 50 deaths. That’s 450 fewer deaths due to predation, which naturally leads to a higher surviving bird population.
So, the mild winter indirectly caused a larger-than-usual bird population by reducing predation through decreased feeder usage.
Hope that helps clarify things—this one’s a bit tricky!
May be a little late but the predators coming into this answer choice is what reinforces this as the right answer. We are told in the stimulus that mild winters allow bird species to forage naturally, which is why the proportion of birds visiting feeders has decreased.
We are then told in this answer choice that birds that attend feeders are more vulnerable to predators than when they forage naturally. Well... If less birds are visiting feeders, wouldn't that mean less are vulnerable to predators. Here I made an assumption that because they are now foraging naturally, their population will either remain the same, or increase, given that birds will mate, but there will be less of a negative impact on their population.
For that reason, we can determine that C is strengthening our explanation, simply because the mild weather is leading to less feeder visits from birds, reducing vulnerability of being eaten.
For strengthening questions, are the answers that mirror the conclusion (like answer choice A) wrong because they just mirror the conclusion rather than strengthen it?
@sopmarsie09 Yes, we are looking for an answer that strengthens the reasoning. We need to strengthen the support relationship and re-stating the conclusion doesn't do that.
I see why C is correct given the explanation of the stimulus.
But I don't understand how in the world we're to interpret the stimulus in that way. Stimulus directly says that attrition accompanies migration. It doesn't mention or refer in any way to feeding places. And reasonable inference of that would be something like that birds die during migration for whatever reason.
Please help. I don't get how we're to link attrition accompanying migration with feeding places and being vulnerable to predators.
This question is a tough one! So, we should treat the premises as two instances that have occurred as a result of the mild winter. 1. Birds are going to bird feeders less and foraging naturally, and 2. Birds are staying in their summer ranges and not dying as a result of the migration. These two premises support our conclusion that the mild winter last year has caused an increase in the bird population this year. All we have to do is strengthen the support of the premises to the conclusion - that's it! We don't have to link the attrition accompanying migration with feeding places etc., we just have to find one of these or both premises and bolster the support to the conclusion.
So, if we look at the premises, one of them is that because of the mild winter, this has allowed birds to forage naturally. Additionally, there are fewer birds visiting bird feeders as a result. This premise doesn't really support anything, it just seems like a fun fact - why should we care that birds are now visiting bird feeders less? In comes the correct answer choice C, which clarifies and further supports our conclusion by stating that birds are more at risk at bird feeders. So, since they're foraging naturally and not vulnerable at bird feeders, this has led to an increased bird population, supporting our conclusion.
Question - could you reasonably argue that just because the bird population increased over the winter, doesn't mean it increased over the entire year? I realize that doesn't show up in the ACs but wondering if that is a valid gap to identify.
I think it's a potential chronology gap, just because the bird population increased after the mild winter doesn’t necessarily mean it remained higher throughout the year.
Would this be a valid gap to identify? Yes, but with an important distinction:
1. If this were a Weaken question, this could be a great angle to attack the argument.
2.However, in a Strengthen question, we’re looking for ways to reinforce the idea that the mild winter was responsible for a sustained increase in population.
I got C but I wanted it to be B so bad :( it would make so much more sense that they are mating more often since there are so many of them in the same place!!!!!

how would you do this question if you do not know what "attrition" means?
I feel that I run into issues with not knowing the meaning of a word and then it impacts my ability to solve the question accurately.
@IsabelSafar It's dumb but I've used this strategy for every test I've ever taken. Substitute the unknown word with a nonsense word, and you can get a good idea of how the word is being used, if not it's definition.

Waffles must be bad. Its implied that if there are waffles accompanying migration, there's less birds at the end of the migration.

im having a hard time trying to figure out when it would be appropriate/good use of time to do a chain

@DanielleMeuret Thank you. This tells me that you really have to pay attention to the structure of the logic and conclusion in the stimulus.
how is a bird feeder more dangerous than in the wild??
@SMRegalado valid thought, however we have to put our inherent knowledge of things aside when the question stem says “if true”
@destinyMejia Except when we the answers require us to make reasonable assumptions?
@SMRegalado Reasonable assumptions that don't contradict the "truth" of the answer choice. If the prompt says "if true" then it doesn't matter if the choice says "Mars is made up of moonbeams," we can't assume that it is incorrect just because in the real world it IS incorrect.
