Sentence 1:

The two cats could be ______ only by the number of rings on their tails; otherwise, they were exactly alike.

- a. separated
- "Separated" means to divide or distinguish something into parts. This fits the context because the cats can be distinguished by the number of rings on their tails.

- b. diversified
- "Diversified" means to make something more varied or different. This does not fit the context because the cats are described as "exactly alike."

- c. disconnected
- "Disconnected" means to separate or break apart. This does not fit the context because the sentence is about distinguishing the cats, not separating them.

- d. differentiated
- "Differentiated" means to show differences between things. While this is somewhat related, "separated" is more precise in this context.

Correct Answer: a. separated

Sentence 2:

Despite her ______ dress, she was a simple girl at heart.

- a. sophisticated
- "Sophisticated" means complex or refined. This fits the context because it contrasts with "simple girl at heart."

- b. casual
- "Casual" means informal or relaxed. This does not fit the context because it does not create the contrast implied by the sentence.

- c. shoddy
- "Shoddy" means poor quality or dishonest. This does not fit the context because it does not align with the idea of a "simple girl at heart."

- d. perceptible
- "Perceptible" means noticeable or detectable. This does not fit the context because it does not describe the dress.

Correct Answer: a. sophisticated

- a. liability
- "Liability" refers to a financial obligation or debt. This does not fit the context because it does not describe a tax-related identifier.

- b. exempt
- "Exempt" means free from a duty or requirement. This fits the context because non-profit agencies often have tax-exempt status.

- c. information
- "Information" is too general and does not fit the specific context of a tax-related identifier.

- "Accountability" means being responsible for actions. This does not fit the context because it does not describe a tax-related identifier.

Correct Answer: b. exempt

- a. toll

- b. ado
- "Ado" means fuss or bother. This does not fit the context because it does not convey the sense of pain.

- c. fitness
- "Fitness" means physical or mental well-being. This does not fit the context because it does not relate to the speaker's struggle.

- a. Carefully
- "Carefully" means with great attention and caution. This fits the context because feeding a premature baby requires careful handling.
