1. Last night at the hospital, 76 babies were born. Of the births, 45% were girls. How many boys were born last night? (Round your numbers to the nearest whole number).

• A. 42
• B. 34
• C. 35
• D. 36

Correct answer: A

Rationale: When 45% of the babies were girls, it means the remaining 55% were boys. To determine the number of boys, calculate 55% of 76, which equals approximately 41.8, rounding up to 42. Therefore, 42 boys were born last night at the hospital. Choice B, C, and D are incorrect as they do not reflect the accurate calculation of the number of boys born.

2. Sublimation is the change in matter from solid to gas or gas to solid without passing through a liquid phase. Outside of the laboratory, which solid provides the best example of this?

• A. Iron
• B. Silver
• C. Salt crystal
• D. Dry ice

Correct answer: D

Rationale: Dry ice (solid carbon dioxide) provides the best example of sublimation outside of the laboratory. When dry ice is exposed to normal atmospheric conditions, it changes directly from a solid to a gas without passing through a liquid phase. This process is commonly observed in everyday situations such as creating 'smoke' or 'fog' effects. Choices A, B, and C (Iron, Silver, and Salt crystal) do not undergo sublimation. Iron and Silver melt and then vaporize, while Salt crystal dissolves in water, and the resulting solution evaporates, which involves a liquid phase.

3. Which type of sugar is a disaccharide?

• A. Sucrose
• B. Fructose
• C. Glucose
• D. Galactose

Correct answer: A

Rationale: The correct answer is A, Sucrose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose. When glucose and fructose combine, they form sucrose. Choice B, Fructose, is a monosaccharide, not a disaccharide. Choice C, Glucose, is also a monosaccharide, not a disaccharide. Choice D, Galactose, is another monosaccharide and not a disaccharide.

4. What word is best to substitute for the underlined words in the following sentence? Stu often regarded his roommates’ housekeeping as sloppy and careless.

• A. his
• B. hers
• C. them
• D. their

Correct answer: D

Rationale: The word 'their' is the best substitute for the underlined words in the sentence because it refers to Stu's roommates in a possessive form, indicating that the housekeeping belongs to them. 'His' (Choice A) refers to Stu, not the roommates. 'Hers' (Choice B) is incorrect as it refers to a female possessive form. 'Them' (Choice C) is a pronoun for a group of people but does not show possession, making it unsuitable in this context.

5. Multiply and express as a decimal: 6 × 55 =

• A. 0.0033
• B. 0.033
• C. 0.33
• D. 3.3

Correct answer: D

Rationale: To find the result of multiplying 6 by 55, you perform the operation 6 × 55, which equals 330. To express this product in decimal form, you place the decimal point one place from the right, resulting in 3.3. Therefore, the correct answer is D (3.3). Choices A, B, and C are incorrect as they do not represent the correct decimal equivalent of the multiplication of 6 and 55.
