Help the eccentric roommate complete their dramatic email by dragging the correct prepositions into the blanks.

Dear Alex,

I must apologize for the sudden invasion of plastic garden gnomes in our living room. I know you strongly object to having lawn ornaments indoors. However, I insist on keeping them here, as I have finally succeeded in training them to guard the TV remote from the cat.

Yours truly, Sam

I must apologize for the sudden invasion...

We use "apologize for" when expressing regret about an action or a situation. (We use "apologize to" when referring to the person receiving the apology).

I know you strongly object to having lawn ornaments indoors.

The verb "object" is followed by the preposition "to" when expressing disagreement or disapproval.

However, I insist on keeping them here...

The verb "insist" pairs with the preposition "on" (followed by an -ing verb or a noun) when demanding that something happen.

...as I have finally succeeded in training them...

We use "succeed in" followed by a gerund (-ing) to talk about achieving a desired result.
