Question

In the following question, a sentence is divided into four parts (P,Q,R,S). Rearrange it in the proper sequence in order to make a meaningful sentence.
P: upset the food webs in these forests
Q: which can kill kelp plants and other
R: the pollutants in this runoff include pesticides and herbicides
S: kelp forest species and

• A. PQRS
• B. RQSP
• C. RSPQ
• D. SRQP

Hint:

Start by identifying the independent clause or the subject of the sentence (in this case, "the pollutants" in part R). Then, look for relative clauses (starting with 'which', 'that', 'who') that modify the subject or object. Finally, piece together the remaining parts based on grammatical structure and logical flow.

Answer 1

The Correct Option is B

Step 1: Understanding the Task
The goal is to arrange the four parts (P, Q, R, S) into a logical and grammatically correct sentence about the effects of pollutants on kelp forests.

Step 2: Identifying the Subject and Logical Connections


Part R introduces the main subject of the sentence: "the pollutants in this runoff include pesticides and herbicides". This is a strong candidate for the beginning of the sentence as it sets the context.

Part Q begins with "which," a relative pronoun that must refer to something mentioned just before it. It can refer to the "pesticides and herbicides" from part R. So, R-Q is a logical pair: "...pesticides and herbicides, which can kill...".

Part S completes the idea started in Q. The pollutants can kill "kelp plants and other kelp forest species and...". The "and" at the end of S suggests that another action or verb will follow.

Part P provides this final action: "...upset the food webs in these forests". This is the consequence of killing the kelp forest species. The structure is: kill [object 1] and [object 2] and upset [object 3]. So P follows S.


Step 3: Constructing the Final Sentence
The logical sequence is R-Q-S-P. The complete sentence reads: "The pollutants in this runoff include pesticides and herbicides, which can kill kelp plants and other kelp forest species and upset the food webs in these forests."

Step 4: Final Answer
The only sequence that forms a coherent sentence is RQSP. Therefore, option (B) is the correct answer.
