1. purchased 2. he 3. machinery 4. new 5. has A. 25143 B. 25413 C. 25134 D. 25314

The correct answer is C. 25134.

The first word, “purchased”, is a past tense verb. The second word, “he”, is a pronoun. The third word, “machinery”, is a noun. The fourth word, “new”, is an adjective. The fifth word, “has”, is a verb.

The correct order of the words is:

1. He has purchased new machinery.

The other options are incorrect because they do not follow the rules of English grammar. For example, option A, 25143, is incorrect because the verb “has” comes before the noun “machinery”. Option B, 25413, is incorrect because the adjective “new” comes after the noun “machinery”. Option D, 25314, is incorrect because the verb “has” comes after the adjective “new”.
