Question
In the question given below, a passage is followed by
three statements which may or may not be inferred from the passage. Select the correct combination of statements that can be inferred. A recent study by marine scientists has found that noise pollution from ships disrupts the communication patterns of whales and dolphins. These marine animals rely on sound for navigation, hunting, and social interaction. Increased underwater noise has forced them to either move away from busy shipping routes or alter their vocal behaviour. Researchers have urged stricter regulations on ship noise to protect marine life. 1. Whales and dolphins depend on sound for survival. 2. Shipping activity has a negative impact on marine mammals. 3. Reducing underwater noise could help preserve marine life.Solution
Statement 1 is correct — the passage mentions that whales and dolphins rely on sound for navigation, hunting, and social interaction, meaning sound is essential for their survival. Statement 2 is correct — ship noise disrupts their communication and forces behavioural changes, showing a negative impact. Statement 3 is correct — researchers have urged stricter regulations on ship noise to protect marine life, implying that reducing such noise would help preservation. Thus, the correct answer is D) All 1, 2 and 3.
