Question

Unscrambe the sentence and supply the missing pronoune.
gusta/trabajar/el/a

Answer 1

Let's take an individual look at some of the words we have to work with:

gusta -- like
trabajar -- to work
él -- he

So, at this point, we know that the sentence is trying to say..."He likes to work."

And this is how we say it:

"A él le gusta trabajar."

You see, the missing pronoun that we had to supply was "le."
