1. What is 0.75 as a fraction?

• A. 3/4
• B. 7/10
• C. 15/20
• D. 1/2

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.

2. When writing dialogue, what should you remember to do?

• A. Avoid contractions and informal language to maintain realism.
• B. Use formal vocabulary to sound sophisticated.
• C. Create realistic speech patterns reflecting the characters' personalities.
• D. Focus on descriptive narrative over character interactions.

Correct answer: C

Rationale: When writing dialogue, it is crucial to create realistic speech patterns that reflect the characters' personalities. This approach helps to bring the characters to life, making them more authentic and engaging to the readers. By capturing the unique voices of the characters through their speech, the dialogue becomes more compelling and adds depth to the narrative. Choices A and B are incorrect because avoiding contractions and using formal vocabulary can make the dialogue sound unnatural and stilted. Choice D is incorrect as focusing solely on descriptive narrative without meaningful character interactions can lead to a lack of engagement and depth in the storytelling.

3. How many amino acids can make up a protein?

• A. 10-20
• B. 50-100
• C. 100-500
• D. 1000+

Correct answer: A

Rationale: Proteins are made up of long chains of amino acids, and there are 20 standard amino acids commonly found in proteins. The sequence and arrangement of these amino acids determine the structure and function of a protein. While proteins can vary in size and complexity, the number of amino acids typically ranges from around 10 to 20 in smaller proteins to hundreds or even thousands in larger proteins. Therefore, the range of 10-20 amino acids is the most accurate representation of the number of amino acids that can make up a protein. Choices B, C, and D are incorrect as they provide ranges that are beyond the typical number of amino acids found in proteins and may lead to confusion. The correct answer is A (10-20).

4. Four people split a bill. The first person pays 1/5, the second person pays 1/3, and the third person pays 1/12. What fraction of the bill does the fourth person pay?

• A. 1/4
• B. 13/60
• C. 47/60
• D. 1/4

Correct answer: C

Rationale: To find the fourth person's share, subtract the fractions paid by the first three people from the total bill (1). The first person pays 1/5, the second person pays 1/3, and the third person pays 1/12. Adding these fractions gives 7/15. Subtracting this from 1 gives the fourth person's share as 8/15, which simplifies to 4/5. Therefore, the fourth person pays 4/5 of the bill. Option A (1/4) is incorrect because it does not consider the fractions paid by the first three people. Option B (13/60) is incorrect as it is not the remainder after subtracting the first three fractions from 1. Option D (1/4) is a duplicate of Option A and is also incorrect.

5. Which blood component is responsible for the production of antibodies?

• A. Platelets
• B. Red blood cells
• C. White blood cells
• D. Plasma cells

Correct answer: C

Rationale: White blood cells, specifically B lymphocytes or B cells, are responsible for producing antibodies as part of the immune response. When the body encounters foreign substances (antigens), B cells are activated to differentiate into plasma cells, which then produce antibodies to target and neutralize the antigens. Platelets are involved in blood clotting and not in antibody production. Red blood cells are primarily responsible for carrying oxygen in the blood and do not produce antibodies. Plasma cells are actually differentiated B cells that produce antibodies, but the question asks for the blood component responsible for the production of antibodies, which is the white blood cells.
