51. Which TWO of the following sentences have an underlined segment that is an adverb clause?
Answer: A,E
A, E
Sentences A and E contain underlined segments that are adverb clauses. These clauses modify the verbs in their respective sentences by providing additional information about the timing and conditions of the actions described.
A) You will earn better grades very quickly if you spend more hours studying for exams.
In this sentence, the clause "if you spend more hours studying for exams" functions as an adverb clause, providing a condition under which better grades will be earned. It modifies the verb phrase "will earn better grades," indicating the specific situation that leads to the outcome.
B) Whoever ate the cake with the chocolate frosting should be heartily congratulated.
The segment "whoever ate the cake with the chocolate frosting" does not serve as an adverb clause; rather, it is a noun clause acting as the subject of the sentence. This clause identifies the person who deserves congratulations but does not modify the verb in a way typical of adverb clauses.
C) During morning recess, students are allowed to play whatever game they choose.
The phrase "whatever game they choose" is a noun clause functioning as the object of the verb "play." It does not modify the verb and therefore does not meet the criteria for an adverb clause. The introductory phrase "During morning recess" is a prepositional phrase, not an adverb clause.
D) George Washington is the individual who established the example for future presidents.
The segment "who established the example for future presidents" is a relative clause that provides more information about the subject, George Washington. This clause does not function as an adverb clause, as it does not modify the verb in the sentence.
E) When the students return from recess, the teacher will distribute the supplies.
In this sentence, "when the students return from recess" serves as an adverb clause, indicating the time frame in which the teacher will distribute the supplies. It modifies the verb "will distribute," clarifying when the action will take place.
Conclusion
Thus, sentences A and E are correctly identified as containing adverb clauses, as they both provide contextual information about the actions in their respective sentences. The other options either include noun or relative clauses that do not serve the function of modifying verbs, which is essential for identifying adverb clauses.
