Question
In the question below, two statements (I) and (II) are
given. These statements may be either independent causes or may be effects of independent causes or a common cause. One of these statements may be the effect of the other statement. Read both the statements and decide which of the following answer choices correctly depicts the relationship between these two statements. Question: I. Many urban local bodies in India have recently launched large-scale tree plantation drives across cities. II. Several environmental studies have revealed a sharp rise in air pollution levels and urban heat over the past few years.Solution
Statement II mentions that studies have shown an increase in air pollution and heat in cities. Statement I describes city authorities responding by launching tree plantation drives. It can logically be inferred that the rising pollution and heat (Statement II) have prompted the tree plantation initiatives (Statement I). Thus, Statement II is the cause and Statement I is its effect, making option B the correct answer.
