Which of the following best paraphrases the paragraph in bold?

The 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."


One problem is that lots of places that may have lots of diverse species are hard to get to. Take the ocean, where taxonomists believe 80 percent of species are hiding. Also, the planet has diverse areas with remote places.


Scientists have difficulty finding and identifying over three-quarters of the world's species due to their habitats being out of human reach. Due to deep oceans and isolated locations, many species will go undiscovered.


The depth of the ocean makes it tough to see things.


There is an issue with locating a large number of species because of the ocean.
