Question
A statement is given, followed by two inferences I and
II. You must assume everything in the statement to be true, and on the basis of the information given in the statement, decide which is/are a logical inference(s). Statement: Plastic bags persist in the environment for hundreds of years, gradually releasing toxic chemicals that significantly contribute to environmental pollution. Â Inferences: I. Plastic is a non-biodegradable element. II. The government should either ban the use of plastic or impose a tax on it.Solution
The statement indicates that plastic bags are a major contributor to environmental pollution because they gradually release toxic chemicals harmful to the environment. Based on this, we can infer that plastic does not naturally degrade or disintegrate, making inference I valid. However, the steps the government should take cannot be inferred from the given information, as this is a suggestion for action rather than a logical conclusion. Therefore, inference II does not follow. Â Hence, the correct answer is (A).
