Question

read the sentence. astronomers are able to map the trajectory of the moon as it travels in a curved trail around the earth. which word is closest in meaning to the underlined word? the speed of an object the space an object occupies the path of an object a spinning motion

Explanation:

To solve this, we analyze the context. The sentence says the moon travels in a curved trail around the earth, and "trajectory" is being mapped. "The speed of an object" is about velocity, not path. "The space an object occupies" is volume, not relevant. "A spinning motion" is rotation, not path. "The path of an object" matches the idea of a curved trail (path) the moon takes, so it's closest in meaning to "trajectory".

Answer:

the path of an object
