Reading TEAS Practice Test

1. Which of the following is a logical conclusion that can be derived from the announcement above?

A. The library is planning to purchase more computers to accommodate longer usage.
B. The library is facing budget cuts and implementing the fee to compensate for them.
C. The library has added the fee to discourage patrons from spending too long on the computers.
D. The library is covering its Internet service costs by passing on the fee to patrons.

Correct answer: C

Rationale: The logical conclusion that can be derived from the announcement is that the library has added the fee to discourage patrons from spending too long on the computers. This conclusion is supported by the fact that the library is limiting computer usage to 30 minutes and implementing a fee for extended use. Choice A is incorrect because there is no indication in the announcement that the library plans to purchase more computers. Choice B is incorrect as there is no mention of budget cuts or using the fee to compensate for them in the announcement. Choice D is incorrect as there is no information in the announcement about the library covering its Internet service costs by passing on the fee to patrons.

2. Which element has the highest melting point of any element?

A. Tungsten
B. Iron
C. Platinum
D. Carbon

Correct answer: D

Rationale: Among the choices provided, carbon, in the form of diamond, has the highest melting point of any element. Diamond's strong covalent bonds between carbon atoms make it incredibly resistant to heat and pressure, giving it the highest melting point compared to tungsten, iron, and platinum. Tungsten is known for its high melting point among metals but not as high as carbon. Iron and platinum have lower melting points compared to carbon, making them incorrect choices in this context.

3. Which of the following best describes eosinophils?

A. A type of granulocyte that secretes histamine to stimulate the inflammatory response.
B. The most abundant type of white blood cell that secretes substances toxic to pathogens.
C. A type of granulocyte found under mucous membranes that defends against multicellular parasites.
D. A circulating granulocyte with high phagocytic activity and aggressiveness.

Correct answer: C

Rationale: Eosinophils are best described as a type of granulocyte found under mucous membranes that defends against multicellular parasites. They release toxic substances to combat parasitic infections and play a significant role in allergic reactions and asthma. Histamine secretion to stimulate inflammation is more characteristic of basophils, while high phagocytic activity and aggressiveness are features of neutrophils, not eosinophils. Describing eosinophils as the most abundant type of white blood cell that secretes toxic substances to pathogens is inaccurate since eosinophils specifically target multicellular parasites, not a broad range of pathogens.

4. Where does most of the chemical digestion take place?

A. Large intestine
B. Stomach
C. Small intestine
D. Esophagus

Correct answer: C

Rationale: Most of the chemical digestion occurs in the small intestine. Enzymes in the small intestine break down nutrients into smaller molecules that can be absorbed by the body. The stomach plays a role in digestion by breaking down food mechanically and initiating some chemical digestion, but the majority of nutrient breakdown and absorption happens in the small intestine. The large intestine mainly absorbs water and salts, with little to no digestion taking place there. The esophagus is a muscular tube that helps move food from the mouth to the stomach and does not participate in digestion.

5. Which hormone is responsible for regulating the body's metabolism?

A. Insulin
B. Thyroxine
C. Melatonin
D. Adrenaline

Correct answer: B

Rationale: Thyroxine, also known as T4, is produced by the thyroid gland and plays a vital role in regulating the body's metabolism. Insulin is not responsible for regulating metabolism; instead, it helps regulate blood sugar levels. Melatonin is involved in regulating sleep-wake cycles, not metabolism. Adrenaline, also known as epinephrine, is a stress hormone that prepares the body for fight or flight responses, not primarily involved in metabolic regulation.
