The correct answer is: D. QRPS
The sentence is: “Work is the one thing that is necessary to keep the world going, and without it we should all die.”
The correct sequence is:
Q: Work is the one thing
R: that is necessary
P: to keep the world going
S: and without it we should all die
The other options are incorrect because they do not follow the correct order of the words in the sentence.
A. QPSR: This option puts the word “and” before the word “necessary.” This is incorrect because the word “and” is used to join two independent clauses. In this sentence, the word “that” is used to introduce a dependent clause.
B. RPQS: This option puts the word “necessary” before the word “to.” This is incorrect because the word “necessary” is an adjective that modifies the noun “thing.” The word “to” is a preposition that introduces the infinitive phrase “to keep the world going.”
C. SRPQ: This option puts the word “to” before the word “keep.” This is incorrect because the word “to” is a preposition that introduces the infinitive phrase “to keep the world going.” The word “keep” is a verb that takes a direct object.
I hope this helps!
