TEAS 7 Reading Practice Test

1. When evaluating the credibility of research sources, which of the following is a valid consideration?

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.

2. Which of the following is considered an intensive property?

Correct answer: D

Rationale: Density is an intensive property because it does not depend on the amount of matter present. Intensive properties are independent of the quantity of the substance and remain constant regardless of the size or amount of the sample being measured. Mass, weight, and volume are extensive properties that depend on the amount of substance present. Mass and weight change with the amount of matter, while volume changes as the quantity of the substance changes. Therefore, they are not considered intensive properties.

3. The pancreas secretes digestive enzymes into the small intestine. What enzyme breaks down proteins into amino acids?

Correct answer: D

Rationale: Trypsin is the correct enzyme that breaks down proteins into amino acids. It is produced by the pancreas and released into the small intestine to facilitate protein digestion. Pepsin is an enzyme from the stomach that also breaks down proteins, amylase targets carbohydrates, and lipase works on fats. In this context, since the question specifies the pancreas and small intestine, the correct answer is Trypsin as it is the pancreatic enzyme responsible for protein breakdown in the small intestine.

4. "Ironic" and "serious" are:

Correct answer: B

Rationale: "Ironic" and "serious" are antonyms as they have opposite meanings. 'Ironic' refers to something that is contrary to what is expected or intended, while 'serious' indicates something grave or without humor. Therefore, the correct answer is B. Choice A is incorrect because synonyms are words with similar meanings. Choice C is incorrect as homonyms are words that sound the same but have different meanings, which is not the case for 'ironic' and 'serious'. Choice D is also incorrect as there is a relationship between the two words, making B the correct answer.

5. Cartilage, found in joints and the ear, is a type of:

Correct answer: B

Rationale: Cartilage is a type of connective tissue that provides support and flexibility to various parts of the body, such as joints and the ear. It is composed of cells called chondrocytes embedded in a matrix of collagen and proteoglycans. Epithelial tissue covers body surfaces, muscle tissue is involved in movement, and nervous tissue transmits signals. The correct answer is connective tissue because cartilage serves a supportive function in the body.
