Concept: In a statement-and-conclusion (assertion) reasoning question, you judge how a given statement relates to the facts stated in the passage, using only what the passage explicitly says and never any outside knowledge. The statement is Definitely True or Definitely False only when the passage directly and explicitly confirms or contradicts it; it is Probably True or Probably False when the passage merely implies or partially supports or opposes it without a direct statement.

Application: The passage states, In addition, effective implementation of rainwater harvesting system adds to water resources. The statement to evaluate claims, Rainwater harvesting plays no role in increasing water resources. These are direct opposites: the passage explicitly asserts that rainwater harvesting does add to water resources, while the statement asserts that it does not. Because this contradiction is explicit and direct, not merely inferred, the statement is Definitely False.

Cross-check: If the passage had only hinted at rainwater harvesting's benefit without stating it plainly, the statement would be merely Probably False. Since the passage names rainwater harvesting specifically and states its positive effect in plain terms, the stronger verdict, Definitely False, applies rather than the weaker Probably False.

• Definitely True and Probably True would require the passage to support the statement's claim that rainwater harvesting has no role; the passage does the opposite, so both are ruled out.

• Probably False would fit if the contradiction were only indirect or inferential; here the contradiction is direct, so this option understates the certainty.

• Definitely False fits because the passage's contradiction of the statement is explicit and unambiguous.
