1. What is the overall median of Dwayne's current scores: 78, 92, 83, 97?

• A. 19
• B. 85
• C. 83
• D. 87.5

Correct answer: B

Rationale: To find the median of a set of numbers, first arrange the scores in ascending order: 78, 83, 92, 97. Since there is an even number of scores, we find the median by taking the average of the two middle values. In this case, the middle values are 83 and 92. Calculating (83 + 92) / 2 = 85, we determine that the overall median of Dwayne's scores is 85. Choice A (19) is incorrect as it does not correspond to any value in the given set of scores. Choice C (83) is the median of the original set but not the overall median once arranged. Choice D (87.5) is the average of all scores but not the median.

2. 10^6 m can be expressed as ____.

• A. 1 kilometer
• B. 1 megameter
• C. 1 gigameter
• D. 1 terameter

Correct answer: A

Rationale: The correct answer is A: 1 kilometer. 10^6 meters is equivalent to 1 kilometer, not 1 megameter. The prefix 'kilo-' represents a factor of 10^3 or one thousand, which is the appropriate conversion in this case. Choice B, 1 megameter, would be 10^6 meters squared. Choices C and D, 1 gigameter and 1 terameter, would represent even larger distances, as 'giga-' represents 10^9 and 'tera-' represents 10^12.

3. All of the following are parts of the respiratory system EXCEPT the:

• A. Trachea
• B. Bronchi
• C. Esophagus
• D. Larynx

Correct answer: C

Rationale: The esophagus is part of the digestive system, not the respiratory system. The trachea, bronchi, and larynx are all components of the respiratory system responsible for the passage of air during breathing and speech production. The esophagus, on the other hand, is part of the digestive system, responsible for the transportation of food from the mouth to the stomach through a series of muscular contractions called peristalsis. Therefore, the correct answer is 'Esophagus (C).' Choices A, B, and D are all integral parts of the respiratory system, playing crucial roles in the airway and vocalization processes.

4. What is a condition characterized by an overactive thyroid gland and excessive production of thyroid hormones called?

• A. Diabetes mellitus
• B. Hyperthyroidism
• C. Hypothyroidism
• D. Cushing's syndrome

Correct answer: B

Rationale: Hyperthyroidism is a condition where the thyroid gland is overactive and produces an excessive amount of thyroid hormones. This can lead to symptoms such as weight loss, rapid heartbeat, sweating, and nervousness. Diabetes mellitus is a condition characterized by high blood sugar levels due to either insufficient insulin production or the body's inability to respond to insulin. Hypothyroidism is the opposite of hyperthyroidism, where the thyroid gland is underactive and produces insufficient thyroid hormones. Cushing's syndrome is a disorder that occurs when the body has a high level of the hormone cortisol for a long time.

5. Which of the following is a thesis statement?

• A. While Abel Tasman is the first European credited with seeing New Zealand, James Cook is recognized for mapping the country.
• B. James Cook is recognized for mapping New Zealand.
• C. Abel Tasman was the first European to see New Zealand.
• D. New Zealand was first mapped by James Cook.

Correct answer: A

Rationale: Choice A is the correct answer as it presents a clear thesis statement by comparing the achievements of Abel Tasman and James Cook. It establishes the main argument of the text, which is a key characteristic of a thesis statement. Choice B is too specific and only focuses on James Cook without presenting an argument. Choice C simply states a historical fact without presenting an argument or comparison. Choice D, while related to the topic, does not establish a clear argument or comparison between individuals, making it an incorrect thesis statement.
