The last two video lessons, this one and the one before it are in a different format then the previous five lessons or so.... visually this format is way harder to follow than the previous format that didn't rely on handwritten words on the screen. I'm going to have to watch a few more times
Speaking very technically, taking (2) to be true (A massive algae bloom starved the dolphins) does not necessarily end our search. While the dolphins may have been starved, could something else not have killed them while they were starving? An analogous situation would be one dying of a gunshot wound while they had the flu. You may very well think that the flu was the cause of their death (or caused the thing which causes their death), but we should be careful about assuming that one thing (however likely for death) guarantees their death, especially when an intervening phenomenon may break the chain of causation. This may be a pedantic point, but one I found worth mentioning.
When we say identify an alt. hypo, is this us creating it in our head? Or reading between the lines of the question and finding an alt. hypo. That's implied by the question?
on the exam, we will be ask to weaken (or find true explanation for) the argument. All answer choices could be potential alternative hypothesis. The correct alternative hypothesis (answer choice) will be the one that, when it's true, explains the original phenomenon (and potentially strengthen the causal relationship? idk about this part). And it will weaken the original argument since the original conclusion (hypothesis) is no longer supported by the premises (phenomena).
"Answer choices will often declare those hypotheses to be either true or false." Can we see an example of this? I'm confused on how we will know if an alternate hypothesis is true or not.
"All Mr. Fat Cat did was eat trash salmon already on the kitchen floor. And that's something we can all relate to." I live for these little humor gems.
I am confused. The point of an alternative hypothesis is to test the strength of the argument? If so, do we come up with these alternative hypothesis ourselves after reading the argument? or are the alternative hypothesis going to be the ones present as answer choices?

1. Weaken questions
Ask: Is there another reason this could have happened?
If an answer introduces a different cause, it weakens.
You’ve shown the author may be wrong about why it happened.
2. Strengthen questions
Ask: Does this rule out another reason?
If an answer eliminates a plausible competing cause, it strengthens.
The original explanation now has less competition.

Finally justice for Mr. Fat Cat!! It only took hours worth of content, but he finally isn't the scapegoat <3
Don't tell me you've never done that LOLLLLLLLL

Mmmmm eating trash salmon off the kitchen floor so tasty
This video talks about alternative hypothesis. https://www.youtube.com/watch?v=2IZfmzq69iM
Hypothesis or in other words, the conclusion, right?
Here's how I see it and maybe a bit easier to understand
Fat Cat vs kids example
Suppose the trash bin was knocked over. The original explanation is: Fat Cat did it.
Now, we introduce an alternative hypothesis: The kids knocked over the bin.
If we take this alternative hypothesis as true, we don’t need the Fat Cat explanation anymore. We know why the trash fell over—it was the kids.
Result: The original argument (blaming Fat Cat) is weakened.
True alternative hypothesis: Weakens the original argument.
False alternative hypothesis: Strengthens the original argument by ruling out other possibilities.
When we say identify an alt. hypo, is this us creating it in our head? Or reading between the lines of the question and finding an alt. hypo. That's implied by the question?

More examples for this lesson or a quick skill builder would be helpful.
For this lesson, my takeaway is that:
on the exam, we will be ask to weaken (or find true explanation for) the argument. All answer choices could be potential alternative hypothesis. The correct alternative hypothesis (answer choice) will be the one that, when it's true, explains the original phenomenon (and potentially strengthen the causal relationship? idk about this part). And it will weaken the original argument since the original conclusion (hypothesis) is no longer supported by the premises (phenomena).
Can someone correct me if I'm wrong?
Can someone explain this better. I’m still confused…
This section REALLY needs examples.
the "let's review" section really confused me, can someone please provide an example on what this would look like?
I was soo lost; I had to reread this twice to understand. An example in this section would indeed be helpful, please.
"Answer choices will often declare those hypotheses to be either true or false." Can we see an example of this? I'm confused on how we will know if an alternate hypothesis is true or not.
