Concept:The sentence is a jumbled set of clauses that must be arranged logically to form a meaningful statement.
Explanation:The given noun clause "the statement" is incomplete.
The next part must provide the main verb.
Only part S begins with the verb "will be made" and completes the clause: "The statement will be made just once."
Thus, S is the first part.
After S, a conjunction is needed to connect the next idea.
Part P starts with "therefore", a conjunction, so SP is the next pair.
Now, after "you must listen carefully" (from P), the reason "in order to understand" (R) fits logically.
This gives the sequence SPR.
Finally, part Q ("what the speaker has said") acts as the object of "understand", completing the sentence.
Therefore, the proper sequence is S P R Q.
Answer:S P R Q (option A)
