1. What form of radiation is composed of electrons traveling at around 16,000 km/sec?

• A. Alpha radiation
• B. Beta radiation
• C. Gamma radiation
• D. Delta radiation

Correct answer: B

Rationale: Beta radiation is composed of high-energy electrons (β- particles) or positrons (β+ particles) traveling at considerable speeds. In this case, the electrons traveling at around 16,000 km/sec align with the characteristics of beta radiation, making it the correct choice. Alpha radiation consists of helium nuclei, gamma radiation is electromagnetic radiation of high frequency, and delta radiation is not a recognized form of radiation, making them all incorrect choices.

2. What does intact mean?

• A. Damaged
• B. In place, unharmed
• C. Destroyed
• D. Incomplete

Correct answer: B

Rationale: The correct answer is B: 'In place, unharmed.' 'Intact' refers to something that is whole, undamaged, or unharmed. Choices A, C, and D are incorrect because they describe states opposite to what intact means. 'Damaged,' 'Destroyed,' and 'Incomplete' all signify a lack of wholeness or harm, which is contrary to the meaning of intact.

3. What type of tissue is fat?

• A. Connective
• B. Muscle
• C. Nervous
• D. Epithelial

Correct answer: A

Rationale: Fat is a type of loose connective tissue known as adipose tissue. Adipose tissue primarily functions to store energy and provide cushioning and insulation for organs. While muscle tissue is responsible for movement, nervous tissue transmits nerve impulses, and epithelial tissue covers and protects body surfaces, fat specifically falls under the category of connective tissue.

4. Select the meaning of the underlined word in the following sentence. He made a posthumous donation to the clinic.

• A. Generous
• B. Immense
• C. Postmortem
• D. Time-honored

Correct answer: C

Rationale: The word 'posthumous' in this sentence means occurring or coming into effect after the person's death. It is related to the word 'postmortem,' which also refers to events or actions happening after death. Given the context of the sentence, the most suitable meaning is 'postmortem.' Choice A, 'generous,' does not accurately reflect the meaning of 'posthumous' in the sentence. Choice B, 'immense,' is unrelated to the concept of something happening after a person's death. Choice D, 'time-honored,' is also not synonymous with 'posthumous' and does not fit the context of the sentence.

5. What does 'Obsolete' mean?

• A. Innovative
• B. Outdated
• C. Effective
• D. Advanced

Correct answer: B

Rationale: The correct answer is 'B: Outdated.' Obsolete refers to something that is outdated or no longer in use. 'Innovative' (choice A) means introducing new ideas or methods; 'Effective' (choice C) means successful in producing a desired result; 'Advanced' (choice D) means far on or ahead in development or progress. Therefore, 'Outdated' is the most appropriate antonym for 'Obsolete.'
