1. Raoul has an upcoming school project, and his own computer is not working. He needs to use the library computer, and he has estimated that he will need to be on the computer for approximately an hour and a half. How much of a fee can Raoul expect to pay for his computer use at the library?

• A. $6
• B. $9
• C. $12
• D. $15

Correct answer: C

Rationale: Raoul needs to use the computer for 90 minutes. The first 30 minutes are free, so he would pay for the remaining 60 minutes, which is 4 intervals of 15 minutes each. Each 15-minute period incurs a $3 charge, so for 60 minutes, Raoul would pay 4 x $3 = $12. Therefore, Raoul can expect to pay $12 for his computer use at the library. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. What correction should the student make to the hypothesis: Lengthening the string of the pendulum increases the time it takes the ball to make one complete period?

• A. Turn it into an 'if-then' statement.
• B. Change 'will increase' to 'increases.'
• C. Switch the order of the sentence so that the phrase about the period comes first.
• D. No corrections are needed.

Correct answer: A

Rationale: The correct answer is A. A hypothesis should be structured as an 'if-then' statement for clarity. This format helps to clearly establish the relationship between the variables and the expected outcome. In this case, the student should frame the hypothesis in a way that if a specific action is taken (lengthening the string), then a specific outcome is expected (increasing the time it takes for the ball to make one complete period). 'If-then' statements are fundamental in hypothesis construction as they clearly define the cause and effect relationship being tested. Choice B is incorrect because changing 'will increase' to 'increases' does not address the structural issue of the hypothesis. Choice C is incorrect as switching the order of the sentence does not fundamentally alter the clarity of the hypothesis. Choice D is incorrect as the hypothesis structure can be improved for better understanding and testing, making correction necessary.

3. To which section of the library should Jorgen go to locate these works?

• A. 100
• B. 200
• C. 700
• D. 800

Correct answer: D

Rationale: Jorgen should go to Section 800 to locate The Iliad and The Odyssey by Homer. These works are literary masterpieces and would be categorized under literature in the library. While sections 100, 200, and 700 cover Philosophy and psychology, Religion, and Arts and recreation respectively, they are not the most suitable sections for finding works of literature like The Iliad and The Odyssey.

4. Long bones are one of the five major types of bones in the human body. Which of the following bones are long bones?

• A. Sacrum
• B. Clavicle
• C. Patella
• D. Ulna, Fibula, Humerus

Correct answer: D

Rationale: Long bones are characterized by their elongated shape and include bones like the ulna, fibula, and humerus. These bones are crucial for providing support, structure, and facilitating movement in the human body. The sacrum, clavicle, and patella are not classified as long bones. The sacrum is a triangular bone at the base of the spine, the clavicle is a collarbone, and the patella is the kneecap. While these bones have important functions, they do not fit the definition of long bones due to their shape and structure.

5. Which of these pairs represents an example of convergent evolution?

• A. Humans and chimpanzees
• B. Bats and birds
• C. Dolphins and sharks
• D. Snakes and earthworms

Correct answer: B

Rationale: Convergent evolution refers to the process by which different species independently evolve similar traits or characteristics due to similar environmental pressures. In the case of bats and birds, both have evolved wings for flight despite not sharing a recent common ancestor with wings. Bats are mammals, while birds are avians, yet they both have wings adapted for flight, which is a classic example of convergent evolution. A) Humans and chimpanzees share a common ancestor and have not independently evolved similar traits. C) Dolphins and sharks are not closely related, and their similarities are due to adaptations to their aquatic environment rather than convergent evolution. D) Snakes and earthworms belong to different classes (reptiles and annelids, respectively) and do not share recent common ancestors, making their similarities not a result of convergent evolution.
