Question

which sentence uses a prepositional phrase?○ given the economic and political unrest, the family decided to emigrate.○ ruling brutally, the harsh dictator caused many people to flee the country.○ increasing tensions required that international diplomats begin to negotiate.○ some editorials exposing government corruption were leaked to the public.

Explanation:

A prepositional phrase starts with a preposition (like "given", "to", "in") and includes its object.

• Option 1: "Given the economic and political unrest" is a prepositional phrase starting with the preposition "given".
• Option 2: No prepositional phrase functioning as an introductory or modifying phrase here; "to flee" is an infinitive phrase.
• Option 3: "to negotiate" is an infinitive phrase, not a prepositional phrase.
• Option 4: "to the public" is a prepositional phrase, but the question asks which sentence uses one, and Option 1 has a clear introductory prepositional phrase, which is the correct choice as identified.

Answer:

Given the economic and political unrest, the family decided to emigrate.
