Re-write the following sentences according to the instructions given after each. Make other changes that may be necessary, but do not change the meaning of each sentence.
It is dangerous as well as illegal to drive a motorcycle without a helmet. (Begin: It is not ..................)
Topic: Transformation — 'not only... but also'
Answer
It is not only dangerous but also illegal to drive a motorcycle without a helmet.
"As well as" and "not only... but also" both join two qualities that are BOTH true, so the conversion is a straight substitution.
The correlative pair must be completed exactly: NOT ONLY... BUT ALSO. Writing "not only... and also" is not a pairing that exists in English.
THE TRAP is the word ONLY. Dropping it gives "It is not dangerous but illegal", which says the opposite of the original — that it is illegal and NOT dangerous. The instruction begins "It is not", which is precisely designed to tempt you into that reading.
Note that no inversion is needed here, because "not only" is not at the start of the sentence — "It is" comes first. Compare the 2024 and 2026 papers, where the sentence BEGINS with "Not only" and inversion is required.
