I ruled out B entirely because I assumed that the lemurs in the deciduous forest (less cover) would want to be more active during the day so they have the opportunity to hide and escape from their predators. Thus, I assumed that they would want to sleep more at night because the predators can't see them anyways.

If B were true, then those lemurs would be caught more easily since they have no defense mechanism/reaction.

I chose E because it seemed like the "best choice". The Lemur in the rain forest doesn't have to sleep more during the day compared to the other lemurs because they have more resources to eat; whereas the others only have the leaves, and assuming that there r less leaves in the winter; they have to I dont know, stay up longer to find more food; or they sleep more (I guess during the day) because they don't have enough energy.

For Question #3, I translated it like this:

/bonded pair --> (other 4+--> /available for adoption)

or

/bonded pair and other 4+--> /available for adoption

since Mittens and Nittens are NOT a bonded pair, thus fitting inside the exception above and "triggering" the sufficient condition; wouldn't the rule not apply for them?

I understand that Mittens and Mittens are not a bonded pair and they are "outside" the exception in the stimulus, "unless... part of a bonded pair of cats", but when translating it with the group 3 rule (negating and making it sufficient), then they fit the exception, no?

Can someone explain this please?

I was beating myself up for confusing the sufficient and necessary in the first sentence.

The word "must" triggers the necessary.

This example helped me understand:

To enter the bar, you MUST be 21.

o If you are inside the bar--> you are 21

x If you are 21--> you are in the bar

Disney: Billionaires can access the US Capital. Billionaires who have funded the Republican Party can have direct say in Congress. All other billionaires have to suck Trump's toes. Elon Musk is a billionaire and can access the US Capital. Elon has direct say in Congress. Elon Musk has never funded the republican party. Elon Musk must have sucked Trump's toes.

Detective: There are people screaming, "shots fired" and hiding in the airport. The cartel leader who was in possession of cocaine is lying on the floor with a bullet wound to the chest. A soldier is standing 10 feet away from the body with a gun in his holster and white powder on his face. My hypothesis is that the soldier killed the leader in order to feed his crippling drug addiction.
