Question

Rearrange the following parts to form a coherent paragraph:
a. over much of the Sahara, these formations were covered by Mesozoic deposits,
b. the Sahara sits atop the African Shield,
c. and many of the important regional aquifers are identified with them,
d. which is composed of heavily folded and denuded Precambrian rocks,
e. have remained horizontal and relatively unaltered,
f. because of the stability of the shield, subsequently deposited Paleozoic formations,
Which of the following will be the third statement after rearrangement?

• A. b
• B. c
• C. d
• D. e
• E. f

Hint:

Look for the relative pronoun "which." It almost always follows the noun it describes. In this case, "African Shield" in (b) is directly described by "which is composed..." in (d).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
To rearrange sentences into a coherent paragraph, we look for a logical flow starting with a general subject, followed by modifiers, reasons, and additional details. We identify "links" like pronouns or relative clauses (\textit{which, these, them}).
Step 2: Key Formula or Approach:
1. Introduction: Sentence (b) introduces the main subject (the Sahara and the African Shield). 2. Modifier: Sentence (d) starts with "which," describing the African Shield mentioned in (b). 3. Sequence: Check for logical continuation.
Step 3: Detailed Explanation:
1. (b) The Sahara sits atop the African Shield (Opening).
2. (d) which is composed of heavily folded and denuded Precambrian rocks (Description of the Shield).
3. (f) because of the stability of the shield, subsequently deposited Paleozoic formations (Transition to later formations).
4. (e) have remained horizontal and relatively unaltered (Describes the state of Paleozoic formations).
5. (a) over much of the Sahara, these formations were covered by Mesozoic deposits (Further geological history).
6. (c) and many of the important regional aquifers are identified with them (Closing detail).
The sequence is b-d-f-e-a-c.
Step 4: Final Answer:
The third statement in the sequence is (d).
