Select the correct text in the passage. Which phrase best helps to determine the meaning of the word orient as used in the passage?
Once again Samuel was starting a new school because his family had to move often for his dad's job. Samuel stood on the grassy lawn of the
campus looking at his map of the schoo's buildings, trying to orient himself. HIS Skill at map reading helped hlm quicky locate where he was in
relation to the map, and he soon plotted a route to his first class.

Answer and Explanation: According to the dictionary, the word orient has many meanings, including "to place in any definite position with reference to the points of the compass or other locations" or "to determine the position of in relation to the points of the compass; get the bearings of".

So, the phrase in the passage that best describes it is

"His skill at map reading helped him quickly locate where he was in relation to the map (...)"

"where he was in relation to the map"

Explanation:

option one: "Samuel was starting a new school" shows that he was unfamiliar with the area, but it is more of a cause than an indication of him orienting himself

option two: "stood on the grassy lawn of the  campus looking at his map""  again is more of a cause showing that he's confused, but doesn't directly explain what it means for Samuel to orient himself

option three: "where he was in relation to the map" elaborates directly on how Samuel is trying to orient himself.

The definition of "orient" is "align or position (something) relative to the points of a compass or other specified positions."

In this phase, Samuel is demonstrating what orient means because he is locating where is (in attempt to align his position) relative to the specified position in the map. This phrase and the definition of "orient" is very similar.

option four: "plotted a route to his first class" happens as an effect of orienting.

I can confirm this is correct on Edmentum.
