1. Which of the following is NOT a component of the genitourinary system?

• A. The kidneys
• B. The urethra
• C. The rectum
• D. The bladder

Correct answer: C

Rationale: The rectum is part of the digestive system, not the genitourinary system. The genitourinary system comprises organs involved in reproduction and urine formation and excretion, such as the kidneys, urethra, and bladder. Choices A, B, and D are all components of the genitourinary system. The kidneys filter blood and produce urine, the urethra is a tube that carries urine from the bladder out of the body, and the bladder stores urine before it is excreted.

2. Based on the information in the table showing healthcare spending per capita in a group of African nations, which country experienced the largest increase in dollars spent per capita from 2013 to 2015?

• A. Eritrea
• B. Sudan
• C. Tanzania
• D. Kenya

Correct answer: A

Rationale: Eritrea had the largest increase in healthcare spending per capita from 2013 to 2015. By comparing the data in the table, it is evident that Eritrea had the greatest change in dollars spent per capita during the specified period. Sudan, Tanzania, and Kenya did not experience as significant an increase in healthcare spending per capita as Eritrea did, making them incorrect choices.

3. What property of a substance measures the amount of matter per unit volume?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: C

Rationale: Density is the property of a substance that measures the amount of matter per unit volume. It is calculated by dividing the mass of an object by its volume. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and volume is the amount of space an object occupies. Therefore, in this context, density is the correct answer as it specifically relates to the concentration of matter within a given volume.

4. Why is the electrical conductivity of a strong acid solution higher than that of a weak acid solution?

• A. Strong acids are more concentrated.
• B. Strong acids release more hydrogen ions.
• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: The correct answer is B because strong acids release more hydrogen ions compared to weak acids. This higher concentration of ions in the solution leads to a higher electrical conductivity. Strong acids ionize completely in solution, producing a higher concentration of ions that can conduct electricity, whereas weak acids only partially ionize, resulting in a lower concentration of ions and lower electrical conductivity. Choice A is incorrect because the concentration of the acid does not directly determine its electrical conductivity. Choice C is incorrect as the ability to dissolve salts is not directly related to electrical conductivity. Choice D is incorrect because the pH of the solution, although related to acidity, does not directly determine the electrical conductivity.

5. What do you predict occurred after Mother Jones's publication about child labor in cotton mills?

• A. More children signed up to work in the factories
• B. Cotton factories in the South closed
• C. Laws were passed to prevent child labor
• D. The pay scale for these children was increased

Correct answer: C

Rationale: After Mother Jones's publication detailing the harsh conditions of child labor in cotton mills, it is likely that public awareness increased, leading to public outcry. This heightened awareness and outrage often result in legislative actions being taken. Therefore, it is reasonable to predict that laws were passed to prevent child labor, as the excerpt vividly describes the unsafe and exploitative working conditions faced by children. Choices A, B, and D are incorrect because the publication would not have encouraged more children to work in such harsh conditions, led to the closure of cotton factories, or increased the pay scale for child laborers; instead, it would have prompted societal action to protect children from such exploitation.
