In the question given below, four words are given in bold which may not be placed in their correct positions. Select the correct pair of words that should be interchanged to make the sentence grammatically correct and meaningful.

Rigorous testing and (A) meticulous analysis of (B) disciplines can (C) substantially accelerate development and innovation in (D) hypotheses.

The correct answer is B-D.

Step-by-step Explanation:

Let's analyze the given sentence and the positions of the words in bold:

"Rigorous testing and (A) meticulous analysis of (B) disciplines can (C) substantially accelerate development and innovation in (D) hypotheses."

1. Analyze word placement and context:

• Word (A) meticulous (adjective) correctly modifies the noun "analysis" (meticulous analysis).
• Word (C) substantially (adverb) correctly modifies the verb "accelerate" (substantially accelerate).
• Word (B) disciplines and word (D) hypotheses are both nouns, but their logical placement in the context of scientific inquiry is interchanged.

2. Logical Connection:

• In scientific and academic contexts, testing and analysis are conducted on hypotheses (proposed explanations or theories). Therefore, "analysis of hypotheses" is logically sound.
• Development and innovation take place within academic or research disciplines (fields of study). Therefore, "innovation in disciplines" makes complete sense.

3. Corrected Sentence:

Interchanging (B) disciplines and (D) hypotheses yields the grammatically correct and meaningful sentence:

"Rigorous testing and meticulous analysis of hypotheses can substantially accelerate development and innovation in disciplines."

Thus, the correct pair of words to interchange is B-D.
