1. What is 0.1 mg to mcg?

• A. 100 mcg
• B. 10 mcg
• C. 1000 mcg
• D. 1 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.1 mg is equal to 100 mcg. This conversion is commonly used in medical calculations. Choice B (10 mcg) is incorrect because it would be the conversion from milligrams to micrograms if multiplied by 100, not 10. Choice C (1000 mcg) is incorrect as it would be the conversion from grams to micrograms if multiplied by 1000. Choice D (1 mcg) is incorrect as it represents the original unit without conversion.

2. What prompted Hedy Lamarr to take up inventing?

• A. Boredom from her film roles lacking spoken lines
• B. Formal training in engineering
• C. Her successful inventions like the radio signal technology
• D. Working with Howard Hughes' aviation team

Correct answer: A

Rationale: Hedy Lamarr took up inventing due to boredom from her film roles lacking spoken lines. The extract mentions that to relieve her boredom, Lamarr turned to inventing after her film roles did not provide much dialogue.

3. Which of the following statements represents an EXAGGERATED claim in support of the argument presented in the passage?

• A. In the United States, the foreign language requirement for high school graduation is decided at the state level.
• B. Studying a foreign language has become increasingly important for the global economy.
• C. High school graduates with foreign language credits have been shown to have an increased college acceptance rate.
• D. Students who did not study a foreign language often find themselves unable to obtain a job at all.

Correct answer: D

Rationale: While it is true that studying a foreign language can enhance one's job prospects and competitiveness in the job market, claiming that students who did not study a foreign language often find themselves unable to obtain a job at all is an exaggerated statement. Many factors contribute to employability, and while language skills can be advantageous, they are not the sole determining factor in securing employment.

4. What are substances that stimulate adaptive immunity called?

• A. Peptides
• B. Phagocytes
• C. Prions
• D. Platelets

Correct answer: A

Rationale: Substances that stimulate adaptive immunity are called peptides. Peptides are short chains of amino acids that play a crucial role in activating the immune response by interacting with immune cells such as T cells and B cells. Peptides are important in antigen presentation and recognition, leading to the development of specific immune responses against pathogens. Choice B, phagocytes, are cells that engulf and digest pathogens but are not substances that stimulate adaptive immunity. Choice C, prions, are infectious agents made of misfolded proteins and are not related to stimulating adaptive immunity. Choice D, platelets, are cell fragments involved in blood clotting and have no direct role in stimulating adaptive immunity.

5. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?

• A. Pneumonia
• B. Bronchitis
• C. Emphysema
• D. Pleurisy

Correct answer: B

Rationale: Bronchitis is the correct answer. It is the inflammation of the bronchi, which are the air passages in the lungs. Bronchitis typically presents with symptoms such as a persistent cough, mucus production, and sometimes difficulty breathing. Pneumonia, on the other hand, is an infection that causes inflammation in the air sacs of the lungs, not specifically the bronchi. Emphysema is a chronic lung condition characterized by the gradual destruction of the air sacs in the lungs, resulting in breathing difficulties. Pleurisy refers to inflammation of the pleura, the lining around the lungs and chest cavity, causing chest pain when breathing or coughing.
