Question

add the phrase that completes the thought in the underlined sentence.
the building had a huge curved roof, or dome. the main attraction was a giant zeiss star projector. the machine projected images of the night sky on the 75 - foot dome. looking up, visitors would see 4,500 sparkling stars that would normally be difficult to see.
looking up, visitors would see 4,500 sparkling stars that would normally be difficult to see.
options:

• in the city’s night sky
• through the giant projector
• from the main building
• on the curved roof

Explanation:

We need to find the phrase that logically completes the sentence about the stars visitors see. The context is about stars that are normally hard to see. In a city, light pollution makes stars hard to see in the city’s night sky. "Through the giant projector" is about how they see the projected stars, not the normal visibility. "From the main building" doesn't relate to star visibility. "On the curved roof" is incorrect as stars are in the sky, not on the roof. So "in the city’s night sky" makes sense as it explains where these stars (that are hard to see normally) are located.

Answer:

A. in the city’s night sky
