CHOICES

6

Choice-A

"If you do not glue them properly, it leads to the collapse of the tower."

The sentence lacks grammatical parallelism. It doesn’t maintain consistency in verb tense. "Leads" does not agree in tense with the subsequent "collapse," creating a grammatical inconsistency.

Wrong No change

7

Choice-B

"If you do not glue them properly, it may lead to the collapse of the tower."

The sentence is correct because it uses "may lead to" to express a possibility of the collapse occurring in the future. This formulation communicates a potential consequence if the gluing is not done properly, allowing for uncertainty regarding the outcome.

Correct may lead

8

Choice-C

"If you do not glue them properly, it led to the collapse of the tower."

The sentence is incorrect because it uses "led" instead of "will lead." "Led" suggests the collapse has already happened, while the sentence aims to convey a future consequence.

Wrong led

9

Choice-D

"If you do not glue them properly, it will have led to the collapse of the tower."

The sentence is incorrect because it uses "will have led" instead of the correct "will lead to." "Have led to" implies that the collapse has already occurred, while the intended meaning is a future consequence.

Wrong will have led
