Support/Contrast Question

I came across this question and I think the correct Similar is “by” but it says the correct word is Contrast “transform” . Can anyone explain why is this the case?

What would your prediction for the blank be?

For me it would be something good, the reason I know that is because it transformed (changed) the derelict neighbourhood. So, I am looking for a contrast of the word “derelict”, and the reason I know that is because of the word “transformed”.

Can you share your thoughts?

I think I made a mistake.
I was looking for the words that support/contrast the sentence.
However, as it seems that the “The derelict neighborhood has been completely transformed” is a one idea 1 and “the ___ public park” is another idea 2. And since, Idea 2 is the contrast of the idea 1 we need to look for the word that contrast and as transformed is the word that contrast, we select Transform.

Do you think this explanation correct? Or am I making a mistake.

Yeah, for this activity you pick the word/phrase that tells you whether the blank is supporting or contrasting something.

In this case, the blank would be contrasting “derelict”, and you know that because of “transformed by”

Alright, thanks for the explanation.
