Dermatologists tell us P : that the skin Q : is a finely laminated coating R : whose layered nature S : has inspired comparisons with onions The Proper sequence should be:

The correct answer is: B. PRQS

Here is a brief explanation of each option:

• A. PQRS

This option is incorrect because the sentence does not make sense if the clauses are arranged in this order. The clause “whose layered nature has inspired comparisons with onions” is a subordinate clause that modifies the noun “coating.” The clause “dermatologists tell us that the skin is a finely laminated coating” is the main clause. The main clause should come before the subordinate clause, so this option is incorrect.

• B. PRQS

This option is correct because the clauses are arranged in the correct order. The main clause “dermatologists tell us that the skin is a finely laminated coating” comes first, followed by the subordinate clause “whose layered nature has inspired comparisons with onions.” This option is the only one that makes sense.

• C. PRSQ

This option is incorrect because the clauses are not arranged in the correct order. The main clause “dermatologists tell us that the skin is a finely laminated coating” should come before the subordinate clause “whose layered nature has inspired comparisons with onions.” This option is incorrect.

• D. PSRQ

This option is incorrect because the clauses are not arranged in the correct order. The main clause “dermatologists tell us that the skin is a finely laminated coating” should come before the subordinate clause “whose layered nature has inspired comparisons with onions.” This option is incorrect.
