Question : Select the most appropriate option to fill in the blank.
They probably subsisted on insects and other small _________ invertebrates and perhaps even on aquatic vertebrates.
Option 1: skittish
Option 2: recluse
Option 3: reverent
Option 4: terrestrial
Correct Answer: terrestrial
Solution : The fourth option is correct.
The sentence suggests that the creatures probably survived on insects and other small creatures, and it uses the word
terrestrial
to describe these creatures.
Terrestrial
refers to things related to or inhabiting the land, as opposed to aquatic or celestial (related to space).
Therefore, the correct answer is terrestrial.
