Ahh -- you're doing an Axia test!!

We'll be glad to comment on your answer.

A little hint in determining WHICH answer is correct. Add the verb "do" and it should be clear!

In the given examples, the correct pronoun case to use is "I" instead of "me."

To determine the correct pronoun case, you can follow these steps:

1. Identify the verb or action in the sentence. In this case, it is "knows."
2. Ask yourself who is performing the action of the verb. In this case, it is "my brother."
3. Identify the pronoun that refers to the same person or subject who is performing the action. In this case, it is "I" because it refers to "my brother" who knows more about technology.
4. Use the corresponding pronoun case based on the sentence structure.
- Subject pronouns (I, he, she, we, they) are used when the pronoun is the subject of the sentence or follows a linking verb (e.g., am, is, are).
- Object pronouns (me, him, her, us, them) are used when the pronoun is the object of a verb or preposition.

In example 18a, "than me" is incorrect because it should be "than I." The pronoun "I" is the subject of the verb "knows," so the subjective case "I" should be used.

In example 18b, "than I" is correct because it follows the correct pronoun case rule. The pronoun "I" is the subject of the verb "knows," and it is being compared to the subject of the second clause, "my brother."
