For this case, what we must do is translate the expression into quotation marks to fill in the blank.
The first thing we must observe before translating is that we must do the translation for the plural.
This is because there is more than one black cat.
Translating we have:
I like = Me gustan
Therefore, the sentence in Spanish is:
Me gustan los gatos negros
Answer:
"Me gustan"
Me gustan los gatos negros
