D is also correct. Customs officials don't need authorization to "search documents" at a port of entry. Those writing the LSAT should know that the Fourth Amendment establishes reasonableness.

Can anyone speak to the connection between "on the contrary" and "however" when used in the same sentence? That's what threw me off.

"at least some"

"many of"

"E" infers that all the consequences were preventable. Is that the case based on the premises/argument?

Answer "A" is unbelievably broad. How might one assume "A" is correct when the scope of the prompt only pertains to biology & physics?

Are we supposed to bring in outside knowledge or not? Read between the lines or not?

After watching the explanation, I still don't understand.

E is a BIG assumption regarding competition. This is a terrible argument. The "National Park" system has no competition because the government manages it. Any privatization would likely increase prices for visitors.

"Immediately"

Does this mean ASAP, hours, days, weeks? In my mind, the dinosaurs could have migrated away from the area.

In this question, do most "snow-removal companies who run lawn care" equal companies that run lawn care?

How do we know that it's inadequate?

Are "pain" and "serious pain" assumed to be synonymous?

Cogent...um

"obtain" is not used correctly at all...wipe my hands of this and move forward

"C"

"not textually identical. But are substantively identical as long as you recognize referential phrasing."

If "referential phrasing" changes context, how did those who identified it as a conclusion do so?

"that seemed worth domesticating."

That is a subset of large wild species, correct? "A" refers to all large wild species, making it a necessary assumption, right?

I'm not following.

"E" has a grammar mistake. Is this uncommon on the LSAT?

That is why I did not choose "E" as the answer.
