1. It was —————that gave u the alarm. ( I, me)

It was me that gave u the alarm. I filled it with ME, but it was wrong answer. Please clarify me why should we use I instead of ME.

2. Whom can I trust, if not —————? (he, him). Please explain why should we use him instead of he.

3. He is as good as ———(I, me). I put it as me but it was wrong answer. Please clarify my doubt why should we use I instead of me.

Thank you so much

Disagree with 1 and 3.

The main difference between "me" and "I" is very easy to remember, as it simply refers to the pronoun type. More exactly, "I" is always used as a subject, while "me" is used as an object. This small and simple difference actually dictates in which situations you should use which.

If you rephrase each one so you're reading the very basic thought, you should come up with these:

1. I gave you the alarm. (You wouldn't say, "Me gave you the alarm," right?)

2. I can trust him. (Also, the "m" on "whom" gives this one away.)

3. He is as good as I am. (When comparing, make sure you add both verbs and the choice should be clear.)

Copy and paste this for personal pronouns and study the three paragraphs carefully:

1. Oh, the great "who vs. whom" debate strikes again! In this sentence, we should actually use "I" instead of "me." "It was I that gave you the alarm." Think of it like this: "I gave you the alarm." Now that sounds right, doesn't it? Indirectly, "it was" connects to "I," making "I" the correct choice here.

2. Ah, the age-old question of pronouns! In this case, we should use "he" instead of "him." So the sentence would be: "Whom can I trust, if not he?" Remember, when the pronoun is the subject of a phrase or clause (i.e., doing the action), it should be in the subjective case, like "he." Trust me, it'll sound grammatically on point!

3. Ah, tricky business once again! In this sentence, we should use "I" instead of "me." So it should be: "He is as good as I." This is because "I" is used when it's the subject of a clause, which it is in this case. Remember, "I" represents the subject that performs the verb, while "me" is used for the object that receives the action. So in this sentence, "I" fits the bill!

1. In the given sentence, "It was ————— that gave you the alarm," we should use "I" instead of "me." Here's why:

When we have a verb after "to be" (in this case, "was"), we need to use the subject pronoun (in this case, "I") instead of the object pronoun (in this case, "me").

The phrase "It was I" is an example of subject complement, where "I" is the subject complement of "it." It functions as the subject of the verb "was."

So, the correct sentence is: "It was I that gave you the alarm."

2. In the sentence, "Whom can I trust, if not —————?" we should use "him" instead of "he." Here's why:

In this sentence, "whom" functions as the object of the verb "trust." Therefore, we need to use the object pronoun "him."

The correct sentence is: "Whom can I trust, if not him?"

3. In the sentence, "He is as good as ———," we should use "I" instead of "me." Here's why:

When we compare two things or people using "as...as," we use subject pronouns.

In this sentence, "I" is the subject of the verb "am" and should be used because it refers to the person who is being compared.

So, the correct sentence is: "He is as good as I."
