1. Which object below has the same density?

• A. A block with a mass of 6.5 grams and a volume of 16.25 cm3
• B. A block with a mass of 80 grams and a volume of 32 cm3
• C. A block with a mass of 48 grams and a volume of 22 cm3
• D. A block with a mass of 100 grams and a volume of 250 cm3

Correct answer: A

Rationale: Density is calculated by dividing the mass of an object by its volume. The density of object A is 6.5 g / 16.25 cm3 = 0.4 g/cm3. The density of object B is 80 g / 32 cm3 = 2.5 g/cm3. The density of object C is 48 g / 22 cm3 = 2.18 g/cm3. The density of object D is 100 g / 250 cm3 = 0.4 g/cm3. Objects A and D have the same density of 0.4 g/cm3. Therefore, the correct answer is A as it has the same density as object D, making them the only objects with a density of 0.4 g/cm3.

2. A hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, 5 phlebotomists, 6 receptionists, and 45 physicians. On one particular day, the staff was at only 68% strength. How many people were working that day? (Round to the nearest whole number).

• A. 102
• B. 106
• C. 98
• D. 110

Correct answer: B

Rationale: To find the total staff working that day, add up all the staff members: 25 registered nurses + 75 unlicensed assistants + 5 phlebotomists + 6 receptionists + 45 physicians = 156 staff members. Since the staff was at 68% strength, multiply 156 by 0.68 to get 106. Therefore, approximately 106 people were working that day. Choice A, 102, is incorrect because it underestimates the total staff. Choice C, 98, is incorrect because it is too low. Choice D, 110, is incorrect because it overestimates the total staff.

3. The strength of a magnetic field is measured in units of:

• A. Amperes
• B. Tesla
• C. Volts
• D. Coulombs

Correct answer: B

Rationale: The Tesla (T) is the unit of measurement for the strength of a magnetic field. One Tesla is defined as one weber per square meter. Amperes (choice A) measure electric current, Volts (choice C) measure electric potential, and Coulombs (choice D) measure electric charge, making them incorrect choices for measuring the strength of a magnetic field.

4. Select the meaning of the word 'spurious' in the sentence: 'The researcher’s spurious argument confused even the experts.'

• A. Bogus
• B. Obscure
• C. Baffling
• D. Outrageous

Correct answer: A

Rationale: The word 'spurious' in this sentence means something that is false or not genuine. In this context, the researcher's argument was misleading or deceitful, confusing even the experts. 'Bogus' means not genuine or false, which aligns closely with the intended meaning of 'spurious.' The other choices, 'obscure,' 'baffling,' and 'outrageous,' do not capture the essence of being false or deceitful, making them incorrect in this context.

5. The voice box may be called the ___________.

• A. larynx
• B. lynx
• C. pharynx
• D. phalanx

Correct answer: A

Rationale: The correct answer is A, larynx. The voice box is commonly referred to as the larynx. It is an organ in the neck that contains the vocal cords and is responsible for producing sound. The other options are incorrect: B) lynx is a type of wildcat, C) pharynx is part of the throat involved in swallowing, and D) phalanx refers to the bones of the fingers or toes.
