I have been working on this and am still confused. Which sentence is correct. Using the pronoun case-

A) My brother knows more about technology than me.
B) My brother knows more about technology than I.

I thought it would be best for B and add to it the word do at the end but we are given these two sentences so as written I now think the correct answer is A. Could this be correct.

No, B is correct.

For sentence B, we understand that it means "than I do." You can add "do" if you want.

The correct sentence is: "My brother knows more about technology than I."

To determine the correct pronoun case in this comparison, you can rephrase the sentence to make it clearer. For example, you can expand the sentence as follows: "My brother knows more about technology than I do."

Now, let's break down the explanation:

- The phrase "than me" in option A is using the object pronoun case. Object pronouns, like "me," are typically used when they function as the object of a verb or preposition. However, in this sentence, "I" is functioning as the subject of the verb phrase "do." Therefore, using "me" would be incorrect.

- In option B, "than I" is using the subject pronoun case. Subject pronouns, like "I," are generally used when they function as the subject of a verb. In this sentence, after the verb "knows," the pronoun refers to the same person, so it should also be in the subject form.

- Adding the verb "do" at the end of option B is unnecessary because the verb "knows" already serves its purpose as the main verb in this sentence.

Based on these explanations, the correct sentence is: "My brother knows more about technology than I."
