Question

3. Identify the sentence in which the underlined clause is a noun clause that functions as the object of a preposition.

a.These experts say that the best time to begin a dog’s training is (when the dog is still a puppy.)
b.(Whoever trains a dog) should have experience.
c.Veteran trainers offer a great deal of love and discipline to (whatever dogs they train.)
d. These experts say (that the best time to begin a dog’s training) is when the dog is still a puppy.

Answer 1

B. "whatever dogs they train" is a clause with a subject (they), a verb (train) and a direct object (whatever dogs). The clause acts as the object of the preposition "to": Veteran trainers offer a great deal of love and discipline to [them]. This option is, in fact, the answer.

Answer 2

Noun clause refers to the group of words acting as a noun. They do not form a complete sentence, in other words, these are dependent clauses.

A noun clause can act as an object of preposition also. A preposition is included in a noun clause in order to give further details.

Therefore, the sentence in which the underlined clause is a noun clause that functions as the object of a preposition is:

Veteran trainers offer a great deal of love and discipline to (whatever dogs they train.)

wherein 'to' is the preposition modifying the noun clause "whatever dogs they train."
