3rd paragraph:
One of the main problems is that most of the places that seem to have a lot of diverse species are in places that are hard to get to. One such place is the ocean, where scientists believe some 80 percent of Earth's creatures are hiding at depths too deep for us to study. In addition, many of the planet's most diverse areas are in remote places with few taxonomists.

Which word from the third paragraph best describes the problem facing taxonomists?

Diverse
Ocean
Creatures
Remote
