TEAS English Questions
1. "I would like to go with you; however, I won’t have time." In this sentence, what part of speech is the word "however"?
- A. Preposition
- B. Conjunction
- C. Conjunctive adverb
- D. Subordinating conjunction
Correct answer: C
Rationale: The word "however" in the given sentence functions as a conjunctive adverb. Conjunctive adverbs are used to connect clauses or sentences and show relationships between them. In this case, "however" introduces a contrast between the speaker's desire to go and the lack of time, indicating a shift in the information provided.
2. Homologous structures are similar structures in different organisms that have a common evolutionary origin. An example is:
- A. Butterfly wings and bird wings (analogous structures with different origins)
- B. The arm of a human, the wing of a bat, and the flipper of a whale
- C. The eyes of an octopus and a human (convergent evolution with different origins)
- D. The stinger of a bee and the barb of a cactus (unrelated structures)
Correct answer: B
Rationale: Homologous structures are similar structures found in different organisms that share a common evolutionary origin. The arm of a human, the wing of a bat, and the flipper of a whale are all examples of homologous structures. Despite serving different functions, they share a common underlying structure due to their evolutionary relationship, evidencing a shared ancestry. These structures are modified over time to suit the specific needs of each species. Option A (Butterfly wings and bird wings) refers to analogous structures with different origins. Option C (The eyes of an octopus and a human) describes convergent evolution where traits evolve independently. Option D (The stinger of a bee and the barb of a cactus) are unrelated structures.
3. Which of the following is the most likely weight of a pencil?
- A. 25 kg
- B. 25 cm
- C. 25 mg
- D. 25 g
Correct answer: D
Rationale: The correct answer is 25 g. Pencils are usually lightweight, and their weight is measured in grams. 25 kg (choice A) is too heavy for a pencil. 25 cm (choice B) is a unit of length, not weight. 25 mg (choice C) is too light for a pencil, as pencils typically weigh more than milligrams.
4. Muscles that work together to produce a specific movement are called
- A. Antagonistic muscles
- B. Agonistic muscles
- C. Synergistic muscles
- D. Flexors and extensors
Correct answer: C
Rationale: Synergistic muscles are groups of muscles that work together in a coordinated manner to produce a specific movement. They synchronize their actions to achieve a common goal efficiently. In contrast, antagonistic muscles work in opposing directions, and agonistic muscles, also known as prime movers, are responsible for initiating a movement. Flexors and extensors represent muscles that perform contrasting actions around a joint, such as bending and straightening. Therefore, the correct answer is C - 'Synergistic muscles,' as they collaborate to facilitate a specific movement, unlike the other choices which describe different muscle functions within the body.
5. The metric system is based on what concept?
- A. Multiplication
- B. Powers of 10
- C. Addition
- D. Subtraction
Correct answer: B
Rationale: The metric system is based on powers of 10. This means that units within the system are related by factors of 10, making conversions straightforward by simply shifting the decimal point. The system's simplicity and consistency are derived from this fundamental concept. Choices A, C, and D are incorrect because the metric system's foundation lies in the consistent relationship between units through powers of 10, not through basic arithmetic operations like multiplication, addition, or subtraction.
