1. How should a researcher test the hypothesis that a particular species of bird vocalizes most in the hours around dawn?

• A. Observe a flock of the birds in captivity and record them at two-hour intervals from predawn until sunset for a month.
• B. Observe a flock of the birds in the wild and record them at one-hour intervals from predawn until sunset in several seasons.
• C. Observe a flock of the birds in the wild and record them in predawn and postdawn hours every day for six months.
• D. Observe a flock of the birds in the wild, record them at one-hour intervals for a month, and compare that recording to recordings of other species.

Correct answer: C

Rationale: Observing a flock of the birds in the wild and recording them in predawn and postdawn hours every day for six months would be the best way to test the hypothesis that a particular species of bird vocalizes most in the hours around dawn. This method allows for consistent monitoring of the birds during specific times of interest over an extended period, providing a comprehensive dataset to accurately analyze the vocalization patterns. Options A and B do not focus specifically on dawn hours, making them less suitable for testing the hypothesis. Option D introduces a comparison with other species, which is unnecessary and distracts from the main objective of studying the vocalization pattern of the particular bird species around dawn.

2. A plan for a house is drawn on a 1:40 scale. If the length of the living room on the plan measures 5 inches, what is the actual length of the built living room?

• A. 45 feet
• B. 25 feet
• C. 15 feet
• D. 12 feet

Correct answer: C

Rationale: Since the scale of the plan is 1:40, this means that 1 inch on the plan represents 40 inches in reality. Therefore, the actual length of the living room can be calculated as 5 inches on the plan multiplied by the scale factor of 40, which equals 200 inches. Converting 200 inches to feet gives us 15 feet as the actual length of the built living room. Choice A (45 feet) is incorrect because it miscalculates the conversion from inches to feet. Choice B (25 feet) is incorrect as it does not consider the scale factor provided. Choice D (12 feet) is incorrect as it does not apply the correct scale factor to convert the plan's measurements to reality.

3. What is another word for the kneecap?

• A. patina
• B. patella
• C. pastel
• D. pathogen

Correct answer: B

Rationale: The correct term for the kneecap is patella. It is a small, flat bone that sits at the front of the knee joint and helps in the transmission of force between the thigh and lower leg while providing protection to the knee joint. 'Patina' refers to a green or brown film on the surface of bronze or similar metals, 'pastel' is a pale, soft shade or color, and 'pathogen' is a bacterium, virus, or other microorganism that can cause disease.

4. What is another word for toxin?

• A. Impurity
• B. Element
• C. Remedy
• D. Poison

Correct answer: D

Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.

5. Dogs are part of a larger animal group, the Carnivora. What classification is this?

• A. Kingdom
• B. Class
• C. Order
• D. Genus

Correct answer: C

Rationale: The classification 'Carnivora' refers to an order in the taxonomic hierarchy. In the Linnaean classification system, the order comes below the class but above the family level. Therefore, Carnivora is a higher classification that includes dog species as well as other carnivorous mammals like cats, bears, and weasels. Option A (Kingdom) is too broad and refers to the highest taxonomic rank. Option B (Class) is a lower taxonomic rank than order. Option D (Genus) is a much more specific rank that comes below the family level in the Linnaean hierarchy.
