Q23 - Since the zoo has more

I found this Q pretty tough.

We know there are more animals than enclosures. For those who are confused, an enclosure is a fake habitat that zoo's install that keep things such a tigers, lions or bears in open spaces.

So lets say we have 2 animals and 1 enclosure. This is the absolute minimum we could have for either of these. Why? Because we know we know we have at least 1 enclosure because we know we have animals - and ALL of the animals stay in an enclosure. Therefore, IF animal ---> goes into enclosure.

So at least 1 enclosure necessitates at least two animals because we have more animals than enclosure. Therefore, in this bare minimum scenario, we have 2 animals going into 1 enclosure. This fits nicely with the conclusion drawn in the stimulus, stating that at least one of the enclosures contains more than 1 animal (at the absolute least, 2, as we have here).

(D) fits this well.

In "H", there are fewer families than children. C>F

So we CANNOT do this scenario: if we have 1 child, we have 0 families. Why? Because we know that having a child necessarily means we have a family. IF child ---> belongs to a family. So in this hypothetical, unfortunately, this kid would be an orphan.

So lets try the next best thing.

2 children --> at the most one family. Okay, now this works. Whats it conclude? At least one family has more than one child (at least 2), and here we have it.

(D) begins with the conclusion, which is something to be aware of, while in the stimulus we have it ending more conventionally with the conclusion at the end of the stimulus. This doesn't matter for parallel questions though since we are looking for logical equivalents, and not stimulus structural equivalents.
