Question

The Adirondack mountains, unlike other mountain ranges that lie on fault lines, are in the shape of a dome, largely in due course from a deep uplift under the Earth's crust about a billion years ago.

• A. in due course from a deep uplift under the Earth's crust
• B. because of a deep uplift of the crust of the Earth, which occurred
• C. due to the course from a deep uplift under the Earth's crust
• D. being caused by a deep uplift under the crust of the Earth, occurring
• E. because of a deep uplift, which occurred under the crust of the Earth

Hint:

Choose clear and direct language when explaining cause and effect. Avoid unnecessary complexity.

Answer 1

The Correct Option is B

Step 1: Analyzing the sentence structure.
The sentence should explain the cause of the Adirondack mountains' shape. The most logical and grammatically correct phrasing is "because of a deep uplift of the crust of the Earth, which occurred."

Step 2: Analyzing the options.
- (A) "in due course from a deep uplift under the Earth's crust" is awkward and imprecise, making the sentence less clear.
- (B) "because of a deep uplift of the crust of the Earth, which occurred" is the clearest and most natural phrasing, explaining the cause effectively.
- (C) "due to the course from a deep uplift under the Earth's crust" is awkward and changes the meaning, making it less accurate.
- (D) "being caused by a deep uplift under the crust of the Earth, occurring" is unnecessarily complex and awkward.
- (E) "because of a deep uplift, which occurred under the crust of the Earth" is a bit less fluid than (B) and slightly weaker.

Step 3: Conclusion.
Option (B) is the best choice as it is the most clear and grammatically correct option.
