Aptitude ends 8. Drip irrigation for lawns Q « Previous Aptitude Gardener: When adding lawns for the new house, we should install drip irrigation system in addition to the sprinklers. This will ensure that the lawns don't dry out in case someone forgets to water the lawn and reduce damage in the garden. The cost of installing drip irrigation system is relatively lower when compared to redoing the lawns due to the damage caused by under watering. House owner: Installing drip irrigation systems are very expensive and unnecessary and seem like a wasteful expense. Which of these choices, if true, could best be used to support the Gardener's proposal in the face of the House owner's objection?

Choose one option.
Show answer & explanation
Answer: B. The use of sprinklers can still reduce the longevity of the lawns due to underwatering.

The house owner objects that drip irrigation is unnecessary because sprinklers are already present. Option B supports the gardener by demonstrating that sprinklers alone are insufficient to prevent underwatering, thereby justifying the additional cost of a drip system to protect the lawn's longevity.

Step-by-step Derivation:
Step 1: Analyze the Gardener's argument. The gardener proposes a drip irrigation system as a backup to sprinklers to prevent lawns from drying out and to avoid the high cost of redoing damaged lawns.
Step 2: Analyze the House Owner's objection. The owner claims the system is 'unnecessary' and a 'wasteful expense,' implying that the existing sprinklers are sufficient.
Step 3: Identify the gap. To support the gardener, we need evidence that the current system (sprinklers) is inadequate to prevent the specific problem (underwatering/drying out).
Step 4: Evaluate Option A. '2 ©@OO00' is nonsensical/gibberish text and provides no logical support.
Step 5: Evaluate Option B. 'The use of sprinklers can still reduce the longevity of the lawns due to underwatering' directly addresses the owner's claim that the system is unnecessary. If sprinklers alone cannot prevent underwatering, the drip system becomes a necessary safeguard rather than a waste.
Step 6: Conclusion. Option B provides the logical link required to counter the owner's objection and support the gardener's proposal.
