SAT Question of the Day for October 15, 2026
While the fruit bat Rousettus aegyptiacus relies on echolocation to navigate dark caves, it does not produce ultrasonic clicks the way most echolocating bats do. __________ it generates sound by clicking its tongue against the roof of its mouth, creating broadband pulses audible even to human ears.
Which choice completes the text with the most logical transition?
- A.Instead,Correct answer
- B.Furthermore,
- C.Regardless,
- D.For instance,
Explanation
The passage establishes that Rousettus aegyptiacus does not use ultrasonic clicks and then describes the alternative method it does use. "Instead," correctly signals this contrast between what is expected and what actually occurs. "Furthermore," incorrectly implies the second sentence adds a similar point rather than presenting a contrasting mechanism. "Regardless," suggests the second sentence proceeds despite an obstacle, but the first sentence presents a factual distinction, not an obstacle. "For instance," implies the second sentence is an example of the first, but it is actually describing a contrasting alternative.
How to use this question
Try the question before you read the explanation: cover it, commit to an answer, and then compare your reasoning with the worked solution. If you missed it, note the step where your approach went wrong rather than only the correct letter, and look for that same step the next time you see a similar question.
