1. Lise is doing a research project on the various psychological theories that Sigmund Freud developed and on the modern response to those theories. To which section of the library should she go to begin looking for research material?

• A. 100
• B. 200
• C. 300
• D. 900

Correct answer: A

Rationale: The correct answer is A: '100.' Freud's theories fall under psychology, which is classified under the 100 section according to the Dewey Decimal Classification system. Section 200 is for Religion, 300 for Social sciences, and 900 for History, geography, and biography. Therefore, A is the most appropriate section for Lise to find research material related to Freud's psychological theories.

2. Which of the following is the most likely weight of a pencil?

• A. 25 kg
• B. 25 cm
• C. 25 mg
• D. 25 g

Correct answer: D

Rationale: The correct answer is 25 g. Pencils are usually lightweight, and their weight is measured in grams. 25 kg (choice A) is too heavy for a pencil. 25 cm (choice B) is a unit of length, not weight. 25 mg (choice C) is too light for a pencil, as pencils typically weigh more than milligrams.

3. Which component of the nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles?

• A. Autonomic nervous system
• B. Peripheral nervous system
• C. Somatic nervous system
• D. Sympathetic nervous system

Correct answer: C

Rationale: The correct answer is C: Somatic nervous system. The somatic nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles. This system consists of motor neurons that send signals from the central nervous system to the skeletal muscles, allowing for conscious control over movement. The autonomic nervous system (A) controls involuntary functions like heart rate and digestion, the peripheral nervous system (B) includes all nerves outside the central nervous system, and the sympathetic nervous system (D) is a division of the autonomic nervous system responsible for the fight-or-flight response. Therefore, choices A, B, and D are incorrect as they do not specifically regulate voluntary movements of skeletal muscles, which is a function of the somatic nervous system.

4. What functional group is present in ethers?

• A. Hydroxyl
• B. Carbonyl
• C. Ether
• D. Amine

Correct answer: C

Rationale: The functional group present in ethers is -O-, representing an oxygen atom bonded to two alkyl or aryl groups. Therefore, choice C, 'Ether,' is the correct answer. Choices A, B, and D refer to different functional groups: hydroxyl (-OH), carbonyl (C=O), and amine (NH2), respectively, which are not present in ethers. Ethers are characterized by the oxygen atom bonded to two carbon groups, distinguishing them from the other functional groups mentioned in the choices.

5. What is the name of the long bone found in the upper arm?

• A. Femur
• B. Tibia
• C. Humerus
• D. Radius

Correct answer: C

Rationale: The correct answer is the humerus. The humerus is the long bone located in the upper arm, between the shoulder and elbow. Option A, Femur, is incorrect as it is the long bone found in the thigh. Option B, Tibia, is incorrect as it is a long bone found in the lower leg. Option D, Radius, is incorrect as it is a bone located in the forearm, not the upper arm.
