1. A baseball team won 72 games. This was 90% of the games it played. How many games did it play?

• A. 75
• B. 80
• C. 85
• D. 100

Correct answer: B

Rationale: Let the total number of games be x. If the team won 72 games, which is 90% of the total games played, we can set up the equation: 72 = 0.90 * x. To find x, divide 72 by 0.90: x = 72 / 0.90 = 80 games. Therefore, the baseball team played 80 games in total. Choice A, 75, is incorrect because it is less than 80. Choice C, 85, is incorrect as it is more than 80. Choice D, 100, is incorrect as it is significantly more than the calculated total of 80 games.

2. Why does the author mention 'impact craters' in line 16?

• A. To explain the corrosive effects of atmospheric weathering
• B. To explain why the Moon has no plant life because of meteorites
• C. To show the result of the Moon not having an atmosphere
• D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

3. Which type of muscles are involved in peristalsis?

• A. Smooth muscles
• B. Cardiac muscles
• C. Skeletal muscles
• D. Epaxial muscles

Correct answer: A

Rationale: Peristalsis is a coordinated, wave-like muscular contraction that propels food and other materials through the digestive tract. Smooth muscles are responsible for this movement in the gastrointestinal tract, providing the involuntary contractions needed for peristalsis to occur. Skeletal muscles, cardiac muscles, and epaxial muscles are not directly involved in peristalsis. Cardiac muscles are found in the heart and are responsible for its contraction. Skeletal muscles are attached to bones and control voluntary movements. Epaxial muscles are located along the vertebral column and are involved in the movement and stabilization of the spine.

4. In contrast with triglycerides, phospholipids are lacking one of which of the following components?

• A. Monosaccharide
• B. Glycerol
• C. Phosphates
• D. Fatty acid

Correct answer: B

Rationale: Phospholipids are structurally similar to triglycerides but lack one of the fatty acid chains that triglycerides possess. Triglycerides consist of three fatty acid chains attached to a glycerol molecule, while phospholipids have two fatty acid chains and a phosphate group attached to a glycerol backbone. Therefore, phospholipids are lacking the third fatty acid chain found in triglycerides. Choice A (Monosaccharide) is incorrect because neither triglycerides nor phospholipids contain monosaccharides in their structure. Choice C (Phosphates) is incorrect because phospholipids actually contain phosphates, unlike triglycerides. Choice D (Fatty acid) is incorrect as both triglycerides and phospholipids contain fatty acids, but the number of fatty acid chains differs between the two.

5. Choose the meaning of the word 'inquest' in the following sentence: 'Many interesting discoveries were made at the inquest.'

• A. Tryout
• B. Intake
• C. Autopsy
• D. Checkup

Correct answer: C

Rationale: The word 'inquest' typically refers to a legal investigation or inquiry, especially into the cause of someone's death. In this context, an 'inquest' is associated with conducting an autopsy to determine the cause of death. Choices A, B, and D are incorrect. A 'tryout' refers to a test or trial, 'intake' relates to the process of taking something in, such as food or air, and a 'checkup' is a general medical examination.
