Question

Choose the most appropriate option that is grammatically incorrect :

• A. A growing bodies of evidence shows that simple rules match or beat more complicated analysis across a wide range of decision.
• B. Rules may be developed using sophisticated statistical models or through analysis, but they shouldn’t be difficult to grasp.
• C. Because they are easy to put into practice, simple rules can induce action without unnecessarily limiting oppositions.
• D. All firms must balance two conflicting but equally important demands: efficiency and flexibility.

Answer 1

The Correct Option is A

The grammatically incorrect option is:

• A growing bodies of evidence shows that simple rules match or beat more complicated analysis across a wide range of decision.

Explanation:

1. The phrase "A growing bodies" is incorrect. The correct form should be "A growing body" because "body" must agree in number with the singular article "A". Thus, the correct sentence should be: "A growing body of evidence shows that simple rules match or beat more complicated analysis across a wide range of decisions."
2. The phrase "across a wide range of decision" is also incorrect. The noun "decision" should be plural, as it refers to multiple decisions, hence "across a wide range of decisions" is the correct phrase.
