TEAS Practice Test: Video 1 Answers (25 Questions) — Questions and Answers

Question 1: 'Ubiquitous' most nearly means:

Very old
Rare
Hidden
Found everywhere (Correct answer)

Correct answer: Found everywhere

Ubiquitous means present everywhere. Rare is the opposite idea.

Question 2: 'Maya studied nightly and aced her exam.' Best inference?

Maya dislikes exams
The exam was easy for everyone
Studying helped Maya succeed (Correct answer)
Maya studied only once

Correct answer: Studying helped Maya succeed

The passage connects nightly study to a top result, so studying likely helped. 'Easy for everyone' is not supported.

Question 3: 'Benevolent' most nearly means:

Angry
Kind and generous (Correct answer)
Shy
Careless

Correct answer: Kind and generous

Benevolent means well-meaning and kind. Careless describes a lack of attention, not goodwill.

Question 4: 'Sleep restores memory, repairs tissue, and regulates mood.' Main idea?

Tissue repair is rare
Sleep supports many body functions (Correct answer)
Sleep affects only mood
Memory is the key to health

Correct answer: Sleep supports many body functions

The three details are examples of sleep helping the body. Mood alone is too narrow.

Question 5: 'Reluctant' most nearly means:

Unwilling (Correct answer)
Certain
Tired
Eager

Correct answer: Unwilling

Reluctant means hesitant or unwilling. Eager is its opposite.

Question 6: A pamphlet lists steps for proper handwashing. Its primary purpose is to:

Entertain
Persuade a vote
Inform and instruct (Correct answer)
Criticize a policy

Correct answer: Inform and instruct

Step-by-step directions aim to instruct. Persuasion would use opinion and appeals.

Question 7: What is 15% of 80?

10
16
12 (Correct answer)
14

Correct answer: 12

10% is 8 and 5% is 4, so 12. Choosing 16 would be 20%.

Question 8: What is 3/4 + 1/8?

4/12
7/8 (Correct answer)
1/2
5/8

Correct answer: 7/8

3/4 equals 6/8, and 6/8 + 1/8 = 7/8. Adding tops and bottoms gives the wrong 4/12.

Question 9: Solve for x: 2x + 6 = 18

5
6 (Correct answer)
9
12

Correct answer: 6

2x = 12, so x = 6. Choosing 12 forgets to divide by 2.

Question 10: How many grams are in 2.5 kilograms?

250
25,000
25
2,500 (Correct answer)

Correct answer: 2,500

1 kg = 1,000 g, so 2.5 kg = 2,500 g. 250 is off by a factor of ten.

Question 11: Two parts are in ratio 3:5 and total 40. What is the larger part?

30
25 (Correct answer)
20
15

Correct answer: 25

Each part is 40 / 8 = 5, so the larger is 5 x 5 = 25. 15 is the smaller part.

Question 12: A rectangle is 8 cm by 5 cm. What is its perimeter?

13 cm
26 cm (Correct answer)
80 cm
40 cm

Correct answer: 26 cm

Perimeter = 2(8 + 5) = 26 cm. 40 cm is the area.

Question 13: What is the mean of 4, 6, 8, and 10?

9
8
7 (Correct answer)
6

Correct answer: 7

The sum is 28, and 28 / 4 = 7. 8 would be the median-like middle guess.

Question 14: Which organelle produces most of a cell's ATP?

Ribosome
Lysosome
Golgi apparatus
Mitochondrion (Correct answer)

Correct answer: Mitochondrion

Mitochondria carry out cellular respiration to make ATP. Ribosomes make proteins.

Question 15: Which heart chamber pumps oxygenated blood to the body?

Left ventricle (Correct answer)
Right atrium
Left atrium
Right ventricle

Correct answer: Left ventricle

The left ventricle sends blood through the aorta. The right ventricle sends blood to the lungs.

Question 16: The atomic number of an element equals its number of:

Isotopes
Electron shells
Protons (Correct answer)
Neutrons

Correct answer: Protons

Atomic number is the proton count. Neutrons vary between isotopes.

Question 17: In DNA, adenine pairs with which base?

Guanine
Cytosine
Thymine (Correct answer)
Uracil

Correct answer: Thymine

A pairs with T in DNA. Uracil replaces thymine in RNA, so it is the main distractor.

Question 18: What is the main function of the alveoli?

Gas exchange (Correct answer)
Produce bile
Store air
Filter blood

Correct answer: Gas exchange

Alveoli let oxygen enter and carbon dioxide leave the blood. They do not filter blood.

Question 19: A solution with a pH of 3 is:

Acidic (Correct answer)
A pure base
Basic
Neutral

Correct answer: Acidic

pH below 7 is acidic. Values above 7 are basic.

Question 20: Neither the nurse nor the doctors ___ late.

were (Correct answer)
was
be
is

Correct answer: were

With neither/nor, the verb agrees with the closer subject, 'doctors', so 'were'.

Question 21: Which is correct? The ___ lounge is down the hall (many nurses).

nurses
nurses's
nurses' (Correct answer)
nurse's

Correct answer: nurses'

For plural nouns ending in s, add only an apostrophe: nurses'. Nurse's is singular.

Question 22: The dog wagged ___ tail.

it
its'
its (Correct answer)
it's

Correct answer: its

'Its' shows possession. 'It's' means 'it is'.

Question 23: Which sentence is punctuated correctly?

I was tired, went home.
I was tired, I went home.
I was tired I went home.
I was tired; I went home. (Correct answer)

Correct answer: I was tired; I went home.

A semicolon joins two independent clauses. The comma alone creates a comma splice.

Question 24: The prefix 'hypo-' means:

Across
Within
Under or below (Correct answer)
Over

Correct answer: Under or below

Hypo- means under, as in hypodermic. Hyper- means over.

Question 25: Maria and ___ went to the lab.

me
myself
mine
I (Correct answer)

Correct answer: I

'I went to the lab' works, so 'I' is correct. 'Me' is an object pronoun.
