1. To write the verb "see" in the present perfect tense using the pronoun "I" as the subject, you need to use the auxiliary verb "have" followed by the past participle form of the verb "see".

The correct answer would be C. "I have seen."

Explanation: The present perfect tense is formed by using the auxiliary verb "have" (in this case, "have") followed by the past participle form of the verb (in this case, "seen"). So, in the present perfect tense, the correct form is "I have seen."

2. The kind of adjective that is used most frequently in ordinary speech or writing is the common adjective.

The correct answer is B. Common.

Explanation: Common adjectives, also known as descriptive adjectives, are used to describe nouns in general terms. These adjectives are commonly used in everyday speech and writing to provide basic descriptions of nouns. Examples of common adjectives would include "big," "beautiful," "yellow," and "happy." Proper adjectives, on the other hand, are derived from proper nouns and specifically refer to a particular person, place, or thing. Article and demonstrative adjectives are different types of adjectives that serve specific roles in sentence structure.
