Select the most appropriate option to fill in blank number 4.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. motion.
"Motion" refers to movement or the act of changing position. This fits perfectly in the blank because the flying squirrel's gliding is a type of movement in the air, not an actual flight.
The phrase clarifies that the squirrel is simply moving through the air in a specific or peculiar way.
Hence, option 2 i.e. motion is the correct option.
