The correct answer is: A. PQSR
The sentence is: “He said that what the world needed today was the development of positive attitudes to cope with environmental and psychological stress and strain.”
The first part of the sentence, “He said that,” is a subordinate clause that modifies the main clause, “what the world needed today was the development of positive attitudes to cope with environmental and psychological stress and strain.” The subordinate clause is introduced by the subordinating conjunction “that,” which is followed by the subject of the subordinate clause, “he,” and the verb of the subordinate clause, “said.”
The main clause is “what the world needed today was the development of positive attitudes to cope with environmental and psychological stress and strain.” The subject of the main clause is “what,” which is a pronoun that stands for the entire subordinate clause, “he said that.” The verb of the main clause is “needed,” and the object of the main clause is “the development of positive attitudes to cope with environmental and psychological stress and strain.”
The phrase “environmental and psychological stress and strain” is a noun phrase that modifies the object of the main clause, “the development of positive attitudes.” The phrase is made up of the noun “stress,” the adjective “environmental,” the noun “psychological,” and the noun “strain.”
The correct sequence of the sentence is: A. PQSR.
