Please help me ASAP Recently, an unmanned spacecraft studied the moon's craters. Surprisingly , the moon was found to have the coldest known places in the solar system. Pluto, which is billions of miles farther away, still gets some direct sunlight. However, the craters on the moon do not, resulting in a temperature around 400 degrees F (240 degrees C) below zero. The discovery of these spots is important. It suggests that there might be more water on the moon than scientists originally thought.

The craters are
A frigid
B eroding
C complex
D immense

im not entirely sure, but i think the answer is listing

1.me is the correct answer

if the italicized noun phrase is "the chairman", the correct option is s (subject). this noun phrase performs the syntactic function of subject of the main clause, as it preceeds the verb phrase ("heard") and is the doer of the action.

if the italicized noun phrase is "what was said about the program", the correct option is do (direct object). this noun phrase follows a transitive verb ("heard"), which requires a direct object to fully complete its meaning.

if the italicized noun phrase is "the program". the correct option is op (object of preposition). this noun phrase follows a preposition ("about"), which requires a prepositional object in order to complete its meaning.
