Choose the correct word. 6
1 The mechanic lost/missed his
leg in an accident.
2 Engineers are developing a(n)
artificial/fake eye for the blind.
3 The robot has two individual/
single microprocessors: one
for movement and one for
communication.
4 The new robotic leg will allow/
let the man to walk again.
5 The brain controls/guides all
the organs in the body.
Explanation: "Lost" means that the mechanic no longer has his leg due to the accident. "Missed" would imply that he missed having his leg, which is not the intended meaning in this sentence.
2. The correct word is "artificial".
Explanation: "Artificial" means something that is made or produced by humans, in this case, an artificial eye. "Fake" implies that it is not real or genuine, which would not be appropriate in this context.
3. The correct word is "individual".
Explanation: "Individual" means separate or distinct from others, so it is appropriate to use in the context of microprocessors. "Single" could also be correct here, but "individual" emphasizes the idea that each microprocessor is independent and not connected to the other.
4. The correct word is "allow".
Explanation: "Allow" means to give permission or make possible. In this sentence, the new robotic leg is enabling the man to walk again. "Let" can also be used, but "allow" is a more formal and appropriate choice in this context.
5. The correct word is "controls".
Explanation: "Controls" means to manage or direct. In this sentence, the brain is responsible for managing and guiding all the organs in the body. "Guides" implies giving directions or instructions, but the brain's role is more comprehensive than that, so "controls" is the more appropriate choice.
