1. If 9 out of 75 band members missed practice, what percentage of band members missed practice?

• A. 10%
• B. 12%
• C. 15%
• D. 18%

Correct answer: B

Rationale: To calculate the percentage of band members who missed practice, divide the number of members who missed practice (9) by the total number of band members (75) and multiply by 100. (9/75) * 100 = 12%. Therefore, 12% of the band members missed practice. Choice A (10%) is incorrect because it is not the correct calculation result. Choices C (15%) and D (18%) are also incorrect as they do not reflect the accurate percentage of band members who missed practice.

2. Which type of joint allows for movement in multiple directions?

• A. Hinge joint
• B. Ball and socket joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is a ball and socket joint like the shoulder or hip joint, as it allows for movement in multiple directions, including rotation. This type of joint offers a high degree of mobility due to its structure, where the rounded end of one bone fits into the cup-like socket of another bone. A hinge joint (Choice A) allows movement primarily in one plane, like the elbow or knee. A pivot joint (Choice C) allows for rotation around an axis, seen in the neck joint. A saddle joint (Choice D) enables movements in multiple directions but to a lesser extent compared to a ball and socket joint, found in the thumb joint.

3. Why is an unwanted gift called a white elephant?

• A. It is a good gift to give at the party
• B. Gifts are never unwanted
• C. Siam's rulers punished with the gift
• D. It is rare to get an unwanted gift

Correct answer: C

Rationale: The term 'white elephant' originated from the practice of the kings of Siam (now Thailand) giving rare and sacred white elephants as gifts. These white elephants were highly prestigious but also very expensive to maintain, causing financial burdens on the recipients. The kings of Siam used white elephants as a punishment for those who displeased them. The recipients were required to care for the white elephant in a grand style, resulting in financial liabilities that could make them impoverished. Over time, the term 'white elephant' evolved to describe any valuable item that is burdensome or unwanted. Therefore, choice C is correct. Choices A, B, and D are incorrect because they do not accurately explain the origin and meaning of the term 'white elephant' in the context of unwanted gifts.

4. A car, starting from rest, accelerates at 10 m/s² for 5 seconds. What is the velocity of the car after 5 seconds?

• A. 2 m/s
• B. 5 m/s
• C. 50 m/s
• D. The answer cannot be determined from the information given.

Correct answer: C

Rationale: The velocity of an object can be calculated using the formula: final velocity = initial velocity + (acceleration × time). In this case, the car starts from rest, so the initial velocity is 0 m/s. Given that the acceleration is 10 m/s² and the time is 5 seconds, we can plug these values into the formula to find the final velocity: final velocity = 0 m/s + (10 m/s² × 5 s) = 0 m/s + 50 m/s = 50 m/s. Therefore, the velocity of the car after 5 seconds is 50 m/s. Choice A (2 m/s) and Choice B (5 m/s) are incorrect because they do not consider the acceleration the car undergoes over the 5 seconds, resulting in a final velocity greater than both. Choice D (The answer cannot be determined from the information given) is incorrect as the final velocity can be determined using the provided data and the kinematic equation.

5. Convert 104°F to Celsius.

• A. 40°C
• B. 42°C
• C. 39°C
• D. 35°C

Correct answer: A

Rationale: To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. Plugging in the value, °C = (104 - 32) x 5/9 = 72 x 5/9 = 40°C. Therefore, 104°F is equal to 40°C. Choice A is correct. Choice B is incorrect as it is not the result of the conversion. Choice C is incorrect as it is not the result of the conversion. Choice D is incorrect as it is not the result of the conversion.
