Rearrange the parts of the sentence in correct order.
The researchers
P. performed experiments and developed a model
Q. which explains how the worm's taste sensors
R. to direct its foraging behaviour
S. process information from the environment
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. PQSR.
Logical Flow:
-
The sentence begins with “The researchers” (subject).
-
Then we need to explain what they did: → P. performed experiments and developed a model
-
What does the model do? → Q. which explains how the worm’s taste sensors
-
Then comes S. process information from the environment (continuing the explanation of "how")
-
Finally, R. to direct its foraging behaviour (shows the purpose of the sensors’ processing)
Correct Sequence: PQSR
Final Sentence: The researchers performed experiments and developed a model which explains how the worm's taste sensors process information from the environment to direct its foraging behaviour.
Hence, the chosen option will be correct.
