1 : If you are serious about P : vocabulary building not a hobby, Q : you will have to make R : an absorbing interest, S : increasing your vocabulary, 6 : or even an obsession. The Proper sequence should be:

The correct answer is: A. PQSR

The sentence is about the importance of vocabulary building. The first clause, “If you are serious about vocabulary building,” is followed by the main clause, “you will have to make it an absorbing interest, or even an obsession.” The second clause, “increasing your vocabulary,” is a subordinate clause that provides more information about the main clause.

The correct sequence of the sentence is:

1. If you are serious about vocabulary building
2. you will have to make
3. increasing your vocabulary
4. an absorbing interest, or even an obsession

Option B, PRQS, is incorrect because the subordinate clause “increasing your vocabulary” is placed before the main clause “you will have to make it an absorbing interest, or even an obsession.”

Option C, RQPS, is incorrect because the subordinate clause “increasing your vocabulary” is placed after the main clause “you will have to make it an absorbing interest, or even an obsession.”

Option D, SQPR, is incorrect because the subordinate clause “increasing your vocabulary” is placed before the main clause “If you are serious about vocabulary building.”
