"particular frequency" is misleading. It doesnt mean it always happens, it actually means most times it happens. Can we asusme conditional relationship?
I got 5/5! For me it has been difficult to translate but after I wrote down the indicators for group 1 and 2 it became much easier. I feel like I'm finally understanding.
I think what is happening is that even though the exercise says "Group 2" which is necessary conditions, almost all the questions are actually sufficient condition questions. Actually it's helpful, because it is practice on distinguishing both. Once clear on that, the quiz helps and is straightforward.
I am confused by this. In the necessary indicators Group 2 the words "only", "always", and "must" are used. For question 2, how is "every time" not a necessary condition indicator? Why is a sufficient condition indicator.
I just looked at the conditional indicators and for question 3 Only is a necessary condition not suffieicient, can someone clarify I am not understanding why they are using it in the example as suffiencient when only is necessary
Number 4 confuses me a bit; why if the necessary condition immediately follows the indicator, does it not have "abundant rain falls" on the right side of the arrow? "Abundant rain falls" immediately follows the indicator of "when", so I had it set up as:
hurricanes hit U.S. mainland frequently → abundant rain falls in Sub-Saharan Africa
This is wrong, obviously, but why? The others make sense to me but this one is tripping me up.
I think the contrapositive is actually what helped me with this a lot. Sometimes I would start with that and work backwards to figure out the logic of what the sentence was saying. Maybe won't work with more complex things, but it helped me figure out which one was sufficient and which one was necessary.
hello, i want someone to check my understanding for question 1, "its always sunny in Philly." my understanding was that "its" isn't enough; we need to categorize two ideas, so theres some nuance and its fine. so the main ideas were sunny and Philly. besides, always indicates neccessary condition.
Can someone please explain to me how on number three - the "oral myths that have survived" is a sufficient condition when the indicator before it says "the only"? I thought "Only" was an indicator of a necessary condition.
I feel like the order is not following based on the previous video. It said the logical indicator would then mean the condition after is the necessary condition. However, sometimes on these it is not following. Anyone else agree?
How do you know what idea goes first? Many seem intuitively correct, but I need to rely on logic. Why am tripping up on this? I wrote P then S. Translation rule "the idea immediately following the logical indicator is the necessary condition," which would make it sunny. Is there a rule of order? 😵💫
I think what confused me is I assumed that this exercise would have more focus on the group 2 indicators. So I was switching the parts of the idea and getting the logic wrong. For instance we focused on every, only, when and where and I completely forgot those were group 1 indicators. I think this might've been more helpful if they were to actually give us a skill builder that follows the new terms we were given following the lesson: only if, only when, must etc.
I got question 3 wrong, but reinterpreting the sentence as "Only written-down oral myths have survived" helps since the wording is deceptive.
Another way to look at the question is to imagine the set relationships. Written down myths are the superset, because surviving myths must be in that set (since there are no surviving myths that were not written).
By that principle, "written down" is necessary for the myth's "survive" which is exactly what the sentence is saying. i.e. "survived" is sufficient to say that the myth was "written down".

"The only" is the only sufficient "only" ...helped me immensely to remember that. Lol.

4/5. Both Sufficient and Necessary have only indicators. Didn't see the "the"
5/5
aren't these mostly group 1 words? "the only", "when", "where"
5/5 thankful I took logical reasoning in freshman year of college, otherwise I probably wouldn't have passed any
Can someone clarify why #3 has 'the only' as a group 1 word. According to the lessons, 'only' only appears in group 2.
Number 4 confuses me a bit; why if the necessary condition immediately follows the indicator, does it not have "abundant rain falls" on the right side of the arrow? "Abundant rain falls" immediately follows the indicator of "when", so I had it set up as:

This is wrong, obviously, but why? The others make sense to me but this one is tripping me up.
Necessary Condition (NC) = Superset
Sufficient Condition (SC) = Subset
If SC is met then the NC is also me.
However the NC can be met while the SC is not. (Kamar being late but not getting cited).
This breakdown has helped me sooo much.
The only way I can get all of these questions right is by reading the lesson notes...

Philadelphia → sunny
/sunny → /Philadelphia
Therefore,
(1)philadelphia is always sunny
(2) If its not sunny, its not in Philadelphia
even though 2 is factually incorrect, is this the right way to go about it? please help
hello, i want someone to check my understanding for question 1, "its always sunny in Philly." my understanding was that "its" isn't enough; we need to categorize two ideas, so theres some nuance and its fine. so the main ideas were sunny and Philly. besides, always indicates neccessary condition.
The first one makes sense when I don't think about what he did in the previous example.
Late -> 5+ was written in that order.
Sunny -> Philidelphia. I follow the same logic but apparently it's wrong.
Can someone please explain to me how on number three - the "oral myths that have survived" is a sufficient condition when the indicator before it says "the only"? I thought "Only" was an indicator of a necessary condition.
Anyone help me?
I genuinely think in contrapositives haha. Is this a good thing?
If it rains in Oklahoma, grasshoppers ride motorcycles into the sunset.
/grasshoppers -> /rain OK
rain OK -> grasshoppers.
I feel this could cost me time in negating everything immediately as I read it. please advise.
I feel like the order is not following based on the previous video. It said the logical indicator would then mean the condition after is the necessary condition. However, sometimes on these it is not following. Anyone else agree?
this one tripped me up the most... i couldn't understand the order
