1. Choose the meaning of the word 'yaw' in the following sentence: 'The robotic arm may yaw too much and need adjusting.'
- A. To gape open
- B. To move up and down
- C. To close tightly
- D. To move side to side
Correct answer: D
Rationale: In this sentence, the term 'yaw' refers to a movement where the robotic arm moves side to side. The context suggests that the arm is exhibiting too much of this side-to-side movement and requires adjustment to rectify the issue. Choice A, 'to gape open,' is incorrect as 'yaw' does not imply opening. Choice B, 'to move up and down,' is incorrect as 'yaw' specifically refers to side-to-side movement. Choice C, 'to close tightly,' is incorrect as it does not relate to the movement described in the sentence.
2. Select the correct order of words to fit in the sentence structure: 'The nursing ___ put the Band- ___ on the wound to ___ the nurse.'
- A. aid, aide, aide
- B. aide, aid, aid
- C. aid, aide, aid
- D. aide, aid, aide
Correct answer: B
Rationale: The correct order of words to fit in the sentence structure is 'aide, aid, aid.' 'Aide' refers to a person who assists (nursing aide), while 'aid' refers to help or assistance (Band-aid and aid the nurse). Therefore, the sequence 'aide, aid, aid' correctly completes the sentence. Choices A, C, and D have the incorrect order of words that do not fit the sentence context.
3. The development of the disease was 'insidious'. What does insidious mean in this context?
- A. Gradual
- B. Momentous
- C. Sudden
- D. Innocuous
Correct answer: A
Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.
4. _______ having trouble with _______ new dog.
- A. There, their
- B. Their, there
- C. They’re, their
- D. Their, they’re
Correct answer: C
Rationale: In this sentence, the correct choices are 'They’re' and 'their.' 'They’re' is a contraction of 'they are,' which fits the context of the sentence as it suggests ownership of the dog. 'Their' is a possessive pronoun showing ownership. Choice A is incorrect as 'there' refers to a place and doesn't make sense in this context. Choice B is incorrect as the possessive pronoun 'their' should come before the noun 'dog'. Choice D is incorrect as 'they’re' should be used before the verb 'having trouble' to form a contraction for 'they are'.
5. It's true that children depend on their parents for food, clothing, and ______.
- A. shelter
- B. security
- C. guidance
- D. affection
Correct answer: A
Rationale: Children depend on their parents for providing basic needs like food, clothing, and shelter. 'Shelter' refers to the physical protection and housing that parents are responsible for providing to their children. While security, guidance, and affection are also important aspects of parenting, in the context of the question, the most essential need after food and clothing is shelter.
