Question

Rearrange the following parts to form a meaningful sentence:
(A) into simpler molecules that can be absorbed into the bloodstream
(B) digestion is an intricate process that begins in the mouth
(C) where food is broken down mechanically and chemically
(D) and continues in the stomach and intestines

• A. (B), (C), (A), (D)
• B. (B), (D), (C), (A)
• C. (B), (A), (C), (D)
• D. (C), (B), (A), (D)

Hint:

Always look for "and" (Part D) to see what it connects. Here, it connects "begins in the mouth" with "continues in the stomach."

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Sentence rearrangement (often called Parajumbles) tests logical sequencing, grammatical connectivity, and subject-verb consistency.
In scientific or descriptive passages, the most logical order is usually:
1. Introduction of the Subject.
2. Elaboration of the Process (Chronological or spatial).
3. Final outcome or purpose of the process.
Step 2: Detailed Explanation:
Let's build the sentence step-by-step:
1. Subject Introduction (Part B): "digestion is an intricate process that begins in the mouth".
This must be the opening part because it introduces the main noun ("digestion") and gives us a starting point ("begins"). Every other part of the sentence refers back to this "process."

2. Logical Continuation (Part D): "and continues in the stomach and intestines".
After stating where the process "begins" (B), the most natural logical flow is to state where it "continues."
The conjunction "and" bridges the "mouth" (from B) with the "stomach and intestines" (in D).

3. Relative Clause (Part C): "where food is broken down mechanically and chemically".
The relative adverb "where" refers back to the physical locations mentioned in the previous part (stomach and intestines).
It explains the specific action occurring within those organs.

4. Result/Final State (Part A): "into simpler molecules that can be absorbed into the bloodstream".
This part describes the final state of the food.
The phrase "broken down" in Part C requires a target state, which is "into simpler molecules" in Part A.
This explains the ultimate biological purpose of the entire process described in B, D, and C.

Putting it together: (B) "Digestion begins..." $\rightarrow$ (D) "...and continues..." $\rightarrow$ (C) "...where food is broken down..." $\rightarrow$ (A) "...into simpler molecules."
This sequence is the only one that follows the biological timeline and the rules of English grammar.
Step 3: Final Answer:
The correct and most meaningful sequence is (B) $\rightarrow$ (D) $\rightarrow$ (C) $\rightarrow$ (A), which corresponds to Option (B).
