Tips: Read each choice carefully, then compare it with what you hear.

Why the other options are wrong:

• medical deliveries and deliveries serving remote communities.: Remote communities describe the medical trial's destination. The proposed initial categories are medical and emergency uses.
• commercial deliveries and deliveries serving remote communities.: Commercial delivery is the industry's wider goal. Remote communities belong to the medical example, rather than the proposed initial categories.
• commercial deliveries and deliveries serving other emergencies.: Emergency uses fit the proposal. The other initial category is medical delivery, rather than commercial delivery generally.

Correct Answer: Widespread delivery operates over neighbourhoods, with possible disruption to sleep and outdoor conversation.

Why this is correct: Park models widespread delivery over neighbourhoods and possible disruption from added noise. Convenience-driven demand and lost emissions savings belong to another study.

Tips: Use the passage to identify the complete claim and its context.

Why the other options are wrong:

• Convenience drives extra deliveries, with possible losses of the emissions savings from each trip.: This is the Conference Board’s demand-and-emissions relationship. Park models widespread deployment and its possible noise effects.
• Widespread delivery operates over neighbourhoods, with possible losses of the emissions savings from each trip.: The widespread-deployment scenario matches Park. Lost per-trip savings belong to the separate convenience-driven demand forecast.
• Convenience drives extra deliveries, with possible disruption to sleep and outdoor conversation.: The disruption outcome matches Park. Convenience generating extra orders is the other study’s explanatory condition, rather than Park’s modelled deployment scenario.

Correct Answer: The earlier objection questions whether safeguards fit the surveillance; the later objection questions whether safeguards can be enforced.

Why this is correct: The earlier concern is legislation’s fit to drone surveillance. Critics later challenge whether the proposed camera restrictions can be enforced.

Tips: Use the passage to identify the complete claim and its context.

Why the other options are wrong:

• The earlier objection questions whether safeguards can be enforced; the later objection raises the same practical concern.: Practical enforcement is the later criticism. The earlier objection concerns legislation not designed for this surveillance.
• The earlier objection questions whether safeguards can be enforced; the later objection questions whether safeguards fit the surveillance.: This reverses the two objections. Legal suitability comes first, followed by practical enforcement of the camera recommendation.
• The earlier objection questions whether safeguards fit the surveillance; the later objection raises the same suitability concern.: Legal suitability is the earlier concern. The later objection instead challenges practical enforcement of the camera recommendation.

Correct Answer: put the first service below capacity and the second below capacity.

Why this is correct: The lower rate gives 2,500 deliveries, below 2,600. The upper rate gives 2,700, below 2,800. Both services stay below capacity.

Tips: Identify the relevant source figures before applying the hypothetical conditions.

Why the other options are wrong:

• put the first service above capacity and the second below capacity.: This uses 35% for the first service instead of 25%. Its correct total is 2,500, below capacity.
• put the first service below capacity and the second above capacity.: This uses the unrelated 80% emissions figure for the second service. Its delivery-demand rate is 35%, leaving it below capacity.
• put the first service above capacity and the second above capacity.: This combines the upper-rate substitution for the first service with the emissions-percentage substitution for the second.

Correct Answer: reluctance to engage with concerns raised by other groups.

Why this is correct: The transition describes reluctance to address the concerns. This is an assessment of engagement, rather than uncertainty, divided evaluation or confidence.

Tips: Use the passage to identify the complete claim and its context.

Why the other options are wrong:

• uncertainty about how serious those concerns would prove in practice.: The noise discussion expresses conditional uncertainty about impacts. The transition instead describes reluctance to address concerns.
• ambivalence about those concerns when weighed against the technology’s acknowledged benefits.: The narrator later weighs valuable applications against unresolved concerns. That ambivalence is not the response described at the transition.
• confidence that those concerns would not prevent further advances in the technology.: The narrator expects progress regardless of regulation. This changes that condition to community concerns and assigns the confidence to the transition.

Correct Answer: Rules under development addressed flying beyond visual range; an issued paper addressed camera use.

Why this is correct: The opening describes rules under development for flights beyond visual range. The later issued guidance paper recommends restrictions on camera use.

Tips: Use the passage to identify the complete claim and its context.

Why the other options are wrong:

• An issued paper addressed flying beyond visual range; rules under development addressed camera use.: This assigns the paper to flight range and developing rules to cameras. Both actual status-and-purpose pairings are reversed.
• Rules under development addressed camera use; an issued paper addressed flying beyond visual range.: The developing rules concern flight range, while the issued paper concerns cameras. This preserves the status order but reverses the purposes.
• An issued paper addressed camera use; rules under development addressed flying beyond visual range.: Both status-and-purpose pairings match, but their order is reversed. The developing flight-range rules appear first.
