Information and Ideas / Inferences Difficulty: Easy

In many cultures, a handshake can create trust between people. Engineer João Avelino and his team are designing a robot to shake hands with a human in order to improve human-robot interactions. The robot hand adjusts its movements and pressure to better imitate the feel of a human hand. The researchers want the robot’s handshake to feel realistic because blank

Which choice most logically completes the text?

lifelike handshakes may make people more comfortable interacting with robots.

it’s easier to program a robot to perform handshakes than it is to program a robot to perform some other types of greetings.

people are less likely to interact with robots that don’t look like humans.

the robot in the researchers’ study may have uses other than interacting with humans.

Explanation

Choice A is the best answer. The text says that handshakes create trust, and that the engineers’ goal is to “improve human-robot interactions.” This suggests that they want the robot’s handshake to feel real because they want humans to trust the robot.

Choice B is incorrect. This inference isn’t supported. The text never discusses any other types of greetings, so there is no basis to make this inference. Choice C is incorrect. This inference isn’t supported. The text never discusses the appearance of this robot or any other robots, so there is no basis to make this inference. Choice D is incorrect. This inference isn’t supported. The text never discusses any uses for the robot other than interacting with humans, so there is no basis to make this inference.
