ATI TEAS 7

TEAS Math Practice Test

1. 4.67 miles is equivalent to how many kilometers to three significant digits?

A. 7.514 km
B. 7.51 km
C. 2.90 km
D. 2.902 km

Correct answer: B

Rationale: To convert miles to kilometers, we use the conversion factor of 1 mile ≈ 1.60934 km. Therefore, 4.67 miles * 1.60934 km/mile = 7.514 km. When rounded to three significant digits, the answer is 7.51 km. Choice A of 7.514 km is the correct conversion, but the question asked for the answer to be rounded to three significant digits, making choice B, 7.51 km, the most precise and correct option. Choices C and D are incorrect conversions and do not match the correct conversion of 4.67 miles to kilometers.

2. Which of the following would be the best concluding statement for this passage?

A. States should consider how important foreign languages are in the global economy when making their policies regarding foreign language requirements for high school graduation.
B. Policies regarding a foreign language requirement for high school graduation should take into account the importance of foreign languages for the global economy and the correlation between foreign languages and increased college acceptance rates and employment opportunities.
C. High school graduation requirements should include a foreign language class because of the influence knowledge of a second language has on college acceptance rates.
D. Policies regarding a foreign language requirement for high school graduation should take into account how difficult it is to obtain a job in today's economy for those who do not have knowledge of more than one language.

Correct answer: B

Rationale: Option B provides the most comprehensive and accurate summary of the claims made in the passage. It addresses the significance of foreign languages for the global economy, the impact on college acceptance rates and job opportunities, and the need for policies to consider these factors when determining foreign language requirements for high school graduation. The passage emphasizes the importance of foreign languages in the global economy and the advantages they bring in terms of college acceptance and employment. Option A is less specific and doesn't mention college acceptance rates or job opportunities, making it less comprehensive. Option C focuses only on college acceptance rates and does not touch upon the broader aspects highlighted in the passage. Option D, while mentioning job prospects, does not cover the full scope of the benefits of foreign language proficiency as discussed in the passage.

3. What are Mendel's laws?

A. Law of inheritance, law of expression
B. Law of segregation, law of independent assortment
C. Law of dominance, law of recessiveness
D. Law of mutation, law of crossing over

Correct answer: B

Rationale: The correct answer is B. Mendel's laws consist of the law of segregation, which states that each parent passes one allele for each trait, and the law of independent assortment, which explains that genes for different traits are inherited independently. Choice A is incorrect because 'law of expression' is not one of Mendel's laws. Choice C is incorrect because 'law of dominance' and 'law of recessiveness' do not represent the two main laws proposed by Mendel. Choice D is incorrect because 'law of mutation' and 'law of crossing over' are not part of Mendel's original laws.

4. What do you predict occurred after Mother Jones's publication about child labor in cotton mills?

A. More children signed up to work in the factories
B. Cotton factories in the South closed
C. Laws were passed to prevent child labor
D. The pay scale for these children was increased

Correct answer: C

Rationale: After Mother Jones's publication detailing the harsh conditions of child labor in cotton mills, it is likely that public awareness increased, leading to public outcry. This heightened awareness and outrage often result in legislative actions being taken. Therefore, it is reasonable to predict that laws were passed to prevent child labor, as the excerpt vividly describes the unsafe and exploitative working conditions faced by children. Choices A, B, and D are incorrect because the publication would not have encouraged more children to work in such harsh conditions, led to the closure of cotton factories, or increased the pay scale for child laborers; instead, it would have prompted societal action to protect children from such exploitation.

5. What is the function of white blood cells?

A. To transport oxygen
B. To fight infection
C. To carry oxygen
D. To produce antibodies

Correct answer: B

Rationale: White blood cells play a crucial role in the immune system by fighting infection and protecting the body from foreign invaders. Choice A, 'To transport oxygen,' is incorrect because red blood cells are responsible for transporting oxygen. Choice C, 'To carry oxygen,' is also inaccurate for the same reason. Choice D, 'To produce antibodies,' while related to the immune system, is not the primary function of white blood cells, as their main role is to directly combat infections.
