Sample General Practice Questions
Try these questions from our free General practice tests. The correct answer and an explanation follow each question.
A scientist wants to test the effect of different light colors on the growth rate of a specific type of bean plant. They place identical plants in separate chambers, with each chamber having a different colored light (red, blue, green), but all other conditions (water, soil, temperature) are kept the same. In this experiment, what is the independent variable?
- A. The growth rate of the bean plants.
- B. The type of bean plant used.
- C. The amount of water given to the plants.
- D. The color of the light.
Answer: D. The color of the light.
The independent variable is the factor that the experimenter intentionally changes or manipulates to observe its effect. In this case, the scientist is changing the color of the light to see how it impacts growth. The growth rate is the dependent variable (what is measured), while the plant type, water, and temperature are controlled variables.
Which word correctly fills the blank? 'The committee will ______ its decision next week.'
- A. announce
- B. announse
- C. anounce
- D. anounse
Answer: A. announce
The correct spelling is 'announce'βdouble 'n' and ending in '-ounce.'
The Atacama Desert, one of the driest places on Earth, is located in which continent?
- A. Africa
- B. Asia
- C. Antarctica
- D. South America
Answer: D. South America
The Atacama Desert runs along the Pacific coast of western South America, mainly in Chile and parts of Peru and Bolivia.
Consider the following statements: 1. All roses are flowers. 2. Some flowers are red. Based on these statements, which of the following conclusions is logically valid?
- A. All roses are red.
- B. Some roses are red.
- C. Some red things are not flowers.
- D. No definite conclusion can be drawn about roses and red color.
Answer: D. No definite conclusion can be drawn about roses and red color.
The first statement establishes that roses are a subset of flowers. The second statement says that some flowers are red. However, the 'red' group of flowers could be entirely separate from the 'rose' group of flowers. There is no direct link established between roses and the color red. Therefore, we cannot logically conclude anything about the color of roses from the information given.
