English Grammar
1. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?
- A. important
- B. importantly
- C. more important
- D. most important
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
2. An ancient Egyptian pyramid has a square base with side lengths of 20 meters and a remaining height (after erosion) of 10 meters. Its original height was 30 meters. What was the volume of the pyramid in its original state?
- A. 12000 cu m
- B. 6000 cu m
- C. 18000 cu m
- D. 24000 cu m
Correct answer: A
Rationale: Use the formula for the volume of a pyramid with the original height and base area.
3. Which term refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint?
- A. Isometric contraction
- B. Eccentric contraction
- C. Isotonic contraction
- D. Concentric contraction
Correct answer: d
Rationale: The correct answer is D: Concentric contraction. Concentric contraction occurs when a muscle shortens in length while generating force, resulting in movement at a joint. This type of contraction is commonly seen when lifting a weight in a bicep curl, for example. Isometric contraction, option A, refers to when the muscle generates force without changing length, eccentric contraction, option B, is when the muscle lengthens while generating force, and isotonic contraction, option C, involves the muscle maintaining a constant tension while changing length. Therefore, in the context of muscle movement and joint action, concentric contraction best describes the condition described in the question.
4. Which type of nutrient requires the most complex and lengthy digestion process?
- A. Carbohydrates
- B. Proteins
- C. Fats
- D. Vitamins
Correct answer: B
Rationale: Rationale: Proteins require the most complex and lengthy digestion process among the options provided. When we consume proteins, they need to be broken down into amino acids, which are the building blocks of proteins. This process starts in the stomach with the help of stomach acid and enzymes, continues in the small intestine where more enzymes break down proteins into amino acids, and finally, these amino acids are absorbed into the bloodstream for various bodily functions. Carbohydrates and fats also require digestion, but the process for breaking down proteins into amino acids is more complex and time-consuming. Vitamins, on the other hand, do not require digestion in the same way as proteins, carbohydrates, and fats, as they are already in a form that can be readily absorbed by the body.
5. What does the term "solute" refer to in a solution?
- A. The substance present in the largest amount
- B. The substance that dissolves in the solvent
- C. The liquid portion of the solution
- D. The temperature at which the solution freezes
Correct answer: B
Rationale: The solute is the substance that dissolves in the solvent to form a solution. The other choices do not accurately describe the solute.
6. Colligative properties of solutions depend on the...
- A. Concentration of the solvent
- B. All of the 3 answers given
- C. Chemical identity of the solute
- D. Number of solute particles in solution
Correct answer: D
Rationale: The correct answer is D: 'Number of solute particles in solution.' Colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution, not on the chemical identity of the solute or the concentration of the solvent. This is because the presence of solute particles disrupts the solvent's normal behavior, affecting these properties. Therefore, the number of solute particles in solution directly influences colligative properties, making it the most accurate choice among the options provided.
