1. To determine the sentence type and purpose used most often in expository writing, we need to understand the different types of sentences and their purposes in writing.

a. Simple sentences consist of one independent clause and express a single thought or idea.
b. Compound sentences consist of two or more independent clauses joined by a coordinating conjunction.
c. Complex sentences consist of one independent clause and at least one dependent clause joined by a subordinating conjunction.
d. Compound/Complex sentences consist of two or more independent clauses and at least one dependent clause.

In expository writing, the purpose is typically to provide information or explain a concept. Based on this, the sentence type and purpose used most often in expository writing is the complex sentence (c). Complex sentences allow writers to add depth and complexity to their explanations by including dependent clauses that provide additional information or clarify the main idea.

2. To determine the part of speech referred to in the sentence "Each of the committee members is expected to be there on time," we need to analyze the different options:

a. Noun - names a person, place, thing, or idea.
b. Pronoun - takes the place of a noun in a sentence.
c. Verb - expresses an action, occurrence, or state of being.
d. Adjective - describes or modifies a noun.
e. Adverb - describes or modifies a verb, adjective, or adverb.
f. Preposition - shows a relationship between a noun and other parts of the sentence.
g. Conjunction - joins words, phrases, or clauses together.

In the sentence, "Each" is an indefinite pronoun that refers to each individual committee member. "Of the committee members" is a prepositional phrase that functions as an adjective modifying "each." "Is expected" is the verb phrase, where "is" is the linking verb and "expected" is the past participle of the verb "expect." Finally, "there" is an adverb that modifies the verb "be," and "on time" is a prepositional phrase that functions as an adverb modifying "be there."

Therefore, the answer is b. pronoun, as "each" is the pronoun in the sentence.
