1. Which aspect of writing engages and connects with the audience, igniting emotion?

• A. Ethos
• B. Logos
• C. Pathos
• D. Kairos

Correct answer: C

Rationale: The correct answer is C, 'Pathos.' Pathos refers to the emotional appeal in writing that aims to engage and connect with the audience's emotions. In the provided extract, Charles Dickens appeals to the emotions of the working men and their families, expressing his earnest hope for their involvement in the Mechanic's Institution. Ethos (choice A) relates to ethical appeal, establishing credibility. Logos (choice B) refers to logical appeal, using reason and evidence. Kairos (choice D) pertains to the timeliness or relevance of an argument, considering the opportune moment for persuasion. In this context, Dickens employs pathos to emotionally connect with the audience and convey his message effectively.

2. In the words proactive, progress, and projecting, pro- is a(n) _______ and means _______.

• A. suffix; good/on top of/over
• B. prefix; before/forward/front
• C. affix; after/behind/in back of
• D. prefix; against/under/below

Correct answer: B

Rationale: In the words proactive, progress, and projecting, 'pro-' is a prefix. A prefix is a morpheme added at the beginning of a word to modify its meaning. In this case, 'pro-' means before, forward, or front, indicating a sense of being proactive, making progress, or projecting ahead. Choice A is incorrect as 'pro-' is not a suffix. Choice C is incorrect as 'pro-' is not an affix that goes at the end or in the middle of a word. Choice D is incorrect as 'pro-' does not mean against, under, or below in the given context.

3. In which medium does light propagate at its highest speed?

• A. Air
• B. Water
• C. Glass
• D. Diamond

Correct answer: A

Rationale: Light travels at its highest speed in a vacuum. However, among the options provided, air is the closest medium to a vacuum, making it the correct answer. In general, light travels slower in denser mediums due to interactions with atoms and molecules in the medium. Water, glass, and diamond are denser mediums compared to air, causing light to propagate at slower speeds in these materials, hence making them incorrect choices.

4. What is the control, if any, in this experiment?

• A. There is no control in this experiment
• B. The control is the water
• C. The control is the diet soda
• D. The control is the amount of sunlight provided to the plants

Correct answer: B

Rationale: The correct answer is B: 'The control is the water.' In a scientific experiment, the control group is used as a baseline comparison to evaluate the effects of the variables being tested. Here, the water serves as the control group against which the effects of other substances like diet soda or different amounts of sunlight can be compared. Choice A is incorrect as every experiment should have a control group for comparison. Choice C and D are incorrect as they are not the standard control in this scenario.

5. The pH scale is used to indicate the concentration of:

• A. Hydrogen ions
• B. Oxygen
• C. Salts
• D. Sugar molecules

Correct answer: A

Rationale: The pH scale is a measure of the concentration of hydrogen ions in a solution, representing its acidity or basicity. A lower pH value indicates higher hydrogen ion concentration and acidity, while a higher pH value indicates lower hydrogen ion concentration and basicity. Choice A, 'Hydrogen ions,' is the correct answer because the pH scale specifically measures the concentration of hydrogen ions in a solution. Choices B, C, and D are incorrect as the pH scale is not used to indicate the concentration of oxygen, salts, or sugar molecules.
