Explanation

"Lahore is more polluted than it was ten years ago."

"More... than" is used for comparing two degrees of a quality — in this case, the level of pollution now versus ten years ago.

Explanation

"Who is the prettiest girl in the picture?"

"The prettiest" is the superlative form of "pretty".

When comparing one person out of a group, we use the superlative form of the adjective

"The" is used before superlative adjectives.
