Let’s go through the worksheet step by step.
The task is:
“Circle the correct meaning for each of the underlined words in the passage.”
We are given 6 vocabulary words (numbered 1–6) and two answer choices per word (a or b). We need to pick the correct definition based on how the word is used in the text.

Let’s look at each word one by one, using context from the passage.

1. geologists
In the passage:
> “In 1908, the Grand Canyon was declared a national monument by President Theodore Roosevelt. In 1919, it became a national park. The park is managed by the National Park Service, which is part of the U.S. Department of the Interior.
Geologists have studied the canyon for many years.”
Also earlier:

Now let’s double-check all answers:
1. geologists →
b
2. arid →
a
3. erosion →
a
4. impassable →
a
5. distinct →
b
6. terrain →
b
All make sense with the context in the passage.
Final Answer:
1. b
2. a
