Question

directions: read the passage about drones and answer questions 1-4
new zealand
this drone works like a dog
as humans fret over the possibility of losing their jobs to robots, some animals may want to start
looking for other work too. in new zealand, farmers have begun replacing dogs with drones that
can herd and monitor their livestock. the drone flies above a herd of sheep, cattle, or deer and
projects a loud barking sound, encouraging the animals to move. its especially effective at herding
fast - moving creatures, says jason rentoul of wye hills farm in marlborough, new zealand. it can
also prevent trouble, as sometimes cattle will stand up to the dogs, but they tend to obey
a drone. at wye hills, what takes two hours with two humans and four dogs takes a drone only
45 minutes. but although there are many advantages to the machines, farmers agree that they
cant do everything. \i think there will always be a need for dogs in some situations,\ rentoul says.
livestock can become desensitized to the drone, for starters; in those cases, dogs help keep
things moving. \dogs are very useful,\ he adds, \and unlike drones they dont crash.\

1. after reading the passage above, what is the best central idea for the passage?

a. dogs are more useful than drones in every aspect.
b. drones are soon going to replace all jobs that deal with farming because
farming isnt needed.
c. people arent the only ones that need to worry about losing their jobs; some
animals are being replaced by technology as well.
d. times are changing and technology is advancing.

1. what would be one piece of evidence below to back up the central idea of the

passage?
a. \dogs are very useful, and unlike drones they dont crash.\
b. \as humans fret over the possibility of losing their jobs to robots, some
animals may want to start looking for other work too.\
c. \... what takes two hours with two humans and four dogs takes a drone only
45 minutes.\
d. \livestock can become desensitized to the drone...\

Explanation:

Question 1

• Option a: The passage says drones have advantages (like faster herding) and dogs have their uses (don't crash), so dogs aren't more useful in every aspect. Eliminate a.
• Option b: The passage states drones can't do everything and there's still a need for dogs, so they won't replace all farming jobs. Also, farming is still needed. Eliminate b.
• Option c: The passage starts by saying humans fret about job loss to robots, then animals (dogs) are being replaced by drones in farming. This matches the central idea.
• Option d: The passage focuses on animals being replaced by technology, not just general technology advancement. Eliminate d.

• Option a: This is about dogs' advantage over drones, not about animals being replaced. Eliminate a.
• Option b: This sentence introduces the idea that both humans and animals (dogs) might lose jobs to technology, which backs the central idea of animals being replaced.
• Option c: This is about the efficiency of drones, not about replacement of animals. Eliminate c.
• Option d: This is about a limitation of drones, not about replacement. Eliminate d.

Answer:

c. People aren't the only ones that need to worry about losing their jobs; some animals are being replaced by technology as well.
