1. If someone is disseminating information, what are they doing?

• A. Withholding it
• B. Broadcasting it
• C. Destroying it
• D. Complicating it

Correct answer: B

Rationale: When someone is disseminating information, they are spreading it widely or broadcasting it to reach a larger audience. Therefore, the correct answer is B: 'Broadcasting it.' This process involves sharing information to make it widely known and accessible. Choice A, 'Withholding it,' is incorrect as it means keeping information back rather than sharing it. Choice C, 'Destroying it,' is incorrect as it means to eliminate or get rid of the information, which is the opposite of disseminating. Choice D, 'Complicating it,' is incorrect as it means making something more complex or difficult to understand rather than spreading it.

2. An overt symptom is ___________.

• A. dangerous
• B. hidden
• C. obvious
• D. controlled

Correct answer: C

Rationale: An overt symptom is a symptom that is easily noticeable or observable. It is not hidden or controlled, but rather overt and easily seen or identified by others. Therefore, the correct answer is C, 'obvious.' 'Dangerous' (choice A) does not describe the visibility of a symptom but rather its potential harm. 'Hidden' (choice B) is the opposite of overt, meaning not easily visible. 'Controlled' (choice D) does not relate to the visibility of a symptom but rather implies regulation or management.'

3. How many electrons are in a neutral atom of neon?

• A. 9
• B. 10
• C. 11
• D. 12

Correct answer: B

Rationale: The atomic number of neon is 10, which represents the number of protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons to maintain electrical neutrality. Therefore, a neutral atom of neon contains 10 electrons, matching the 10 protons within the nucleus. Choice A (9 electrons) is incorrect as it doesn't correspond to the atomic number of neon. Choices C (11 electrons) and D (12 electrons) are also incorrect as they do not align with the correct atomic number of neon.

4. Cavitation is a phenomenon observed in fluids when the pressure falls below its:

• A. Boiling point
• B. Density
• C. Freezing point
• D. Vapor pressure

Correct answer: D

Rationale: Cavitation is a phenomenon where vapor bubbles form in a fluid due to pressure dropping below the vapor pressure of the liquid. When this occurs, the bubbles collapse, creating intense shock waves. The pressure falling below the vapor pressure is what triggers cavitation, not the boiling point, density, or freezing point of the fluid. Therefore, the correct answer is 'Vapor pressure,' as it directly relates to the pressure threshold required for cavitation to happen.

5. Multiply: 15 × 52 =

• A. 0.0078
• B. 0.078
• C. 0.78
• D. 7.8

Correct answer: D

Rationale: To find the product of 15 and 52, you simply multiply them together: 15 x 52 = 780. Therefore, the correct answer is 7.8. Choices A, B, and C are incorrect as they represent fractions or decimals much smaller than the correct product of 780.
