Digital SAT® Practice Test 1: Reading and Writing Module 2 (Easy): Question 6 Explanation

Digital SAT Reading and Writing Test 3 Question 6

Which choice completes the text with the most logical and precise word or phrase?

creation
formulation
detection
limitation

Answer:

Explanation

The nocturnal aye-aye lemur is known to locate insects inside trees by tapping on tree bark. In a 2019 study led by Dr. Helena Fitch-Snyder, researchers discovered that this detection is accomplished by sensing the echoes generated from its tapping.

Choice C is the best answer. The text states that the aye-aye lemur taps on tree bark to find insects. The word "detection" means discovery, and it accurately denotes the discovery of their prey.

Choice A: "creation" means the action of bringing something into existence. The text’s description of the lemurs’ search for insects is far from an act of creation.

Choice B: "formulation" means the action of devising. The text does not indicate that the aye-aye planned or invented this action.

Choice D: "limitation" means restriction. It would not make sense, since it would read that they are looking for insects in order to achieve restriction.

✨ Expert's Tip ✨

Connect the researchers' discovery with the purpose of the lemurs’ taps.
