Who else didn't select E for #18 because they thought it was a trap answer?

To go off on a tangent from the LSAT, the statement that "The Indus Valley people were the first to cultivate rice and cotton" is most likely not true.

I don't know about cotton, but there's a copious amount of genetic and archeological evidence to suggest rice domestication and cultivation first occurred thousands of years in the area of modern-day southern China (either the lower Yangtze or Pearl River basin, the theories for the former having an edge) before the introduction of rice to modern-day India. This perhaps coincided with the migration of Austroasiatic peoples from Southeast Asia, whom the proto-Dravidians/whatever other native groups received this crop package from.

So whatever rice plants were available to the natives before this agricultural contact were probably not the source of the first domesticated crops available to them (regardless of any subsequent intermixing between domesticated Sinic/Indochinese and wild Indic rice strains).

There's also the simple fact that this contact probably first occurred in modern-day eastern India, not western, where the Indus Valley civilization was located, even before the formation of that civilization.

Who else got this question wrong because of confusing importers with customs officials?

For me, as weirdly simplistic as D sounds, it was the only answer left after removing the choices that are irrelevant or already stated in the conditional chain.

Did any other history majors waste time with this question because they initially thought C is a trap?

Interested!

The word that critically turned me away from D and towards B was the word "probably" in D.
