TEAS Test English Questions

1. Which of the following sentences best serves as the topic sentence in a paragraph about the history of yoga?

Correct answer: D

Rationale: The correct answer is D because it introduces the historical origin of yoga, which is the main focus of the paragraph. This sentence sets the context by providing a foundational understanding of where and when yoga originated. Choice A talks about the mention of yoga in the Vedas but does not provide information about the historical development of yoga itself. Choice B discusses the travel of yoga masters to the West, which is a later development in the history of yoga and not the starting point. Choice C refers to a shift in yoga philosophy without directly addressing its origins, making it less suitable as a topic sentence compared to choice D.

2. He had to fill out a health history ____ before seeing the doctor.

Correct answer: A

Rationale: The correct answer is 'questionnaire.' A questionnaire is a set of questions used for gathering information. The incorrect choices B, C, and D have misspellings of the word 'questionnaire.' 'Questionaire,' 'questionnare,' and 'questionairre' are not correct spellings and may lead to confusion or misunderstanding. It is essential to use the correct spelling to ensure clear communication in healthcare settings.

3. What is the median of the set of numbers {2, 3, 9, 12, 15}?

Correct answer: B

Rationale: The median represents the middle value in an ordered set of numbers. To find the median, the numbers need to be arranged in ascending order: {2, 3, 9, 12, 15}. Since the set has an odd number of elements, the median will be the middle value, which is 9 in this case. Choice A (3) and Choice D (15) are incorrect as they do not fall in the middle of the ordered set. Choice C (12) is also incorrect as it is not the middle value in this particular set.

4. Which hormone is produced by the thyroid gland?

Correct answer: B

Rationale: The correct answer is B: Thyroxine. The thyroid gland produces thyroxine, a hormone essential for regulating metabolism. Insulin is produced by the pancreas to regulate blood sugar levels. Adrenaline is produced by the adrenal glands to prepare the body for the 'fight or flight' response. Cortisol is produced by the adrenal cortex in response to stress, not by the thyroid gland.

5. Which compound is a component of baking soda and is important for maintaining pH balance in the body?

Correct answer: D

Rationale: The correct answer is D, Sodium bicarbonate. Sodium bicarbonate, commonly known as baking soda, is a compound that plays a crucial role in maintaining pH balance in the body. When ingested, sodium bicarbonate acts as a buffer, helping to regulate the body's pH levels. It is essential for various physiological functions. Choices A, B, and C are incorrect. Potassium, calcium, and sodium are important minerals in the body but are not components of baking soda or directly responsible for maintaining pH balance in the same way as sodium bicarbonate.
