This question tests knowledge of compound words. A single word must join with "paper" to make one word and also join with "lifter" to make another word. Testing "weight": "paper" plus "weight" gives "paperweight", a small object placed on top of papers so they do not blow away, and "weight" plus "lifter" gives "weightlifter", someone who lifts heavy weights competitively.
Checking the remaining choices confirms none work both ways. "Cone" does not combine with "paper" or "lifter" to form standard words. "Light" does not create accepted compounds with either word in this pattern. "Fly" similarly fails to produce recognised English words on both sides.
Since "weight" is the only word that forms two genuine, commonly used English words when combined with "paper" and "lifter", the correct choice is option 2, weight.
Which of the following does not make a sensible word/phrase when added to the given word?
Word: FIRE
