Question

Commercially reared chicken can be unusually aggressive, and are often kept in darkened sheds to prevent them pecking at each other.
A. The birds spent far more of their time - up to a third - pecking at the inanimate objects in the pens, in contrast to birds in other pens which spent a lot of time attacking others.
B. In low light conditions, they behave less belligerently but are more prone to ophthalmic disorders and respiratory problems.
C. In an experiment, aggressive head-pecking was all but eliminated among birds in the enriched environment.
D. Alerting the birds’ environment, by adding bales of wood-shaving to their pens can work wonders.
6. Bales could diminish aggressiveness and reduce injuries; they might even improve productivity, since a happy chicken is a productive chicken.

• A. DCAB
• B. CDBA
• C. DBAC
• D. BDAC

Hint:

For problem-solution para-jumbles, sequence your sentences from proposed solution → proof → supporting details → limitations for a strong structure.

Answer 1

The Correct Option is A

(D) logically follows the opening sentence by introducing an environmental change as a remedy. (C) provides direct experimental evidence showing reduced aggression. (A) supports this by describing the birds’ changed behaviour. (B) offers a cautionary note about the drawbacks of using low-light methods instead. This creates a natural flow from solution → evidence → observation → caution.
