1. When two long, parallel wires carry currents in the same direction, the wires will experience a force of:

Correct answer: D

Rationale: When two wires carry current in the same direction, they create magnetic fields that interact with each other. This interaction results in an attractive force between the wires due to the alignment of their magnetic fields. Choice A is incorrect because the force can be predicted based on the direction of the currents and the magnetic fields produced. Choice B is incorrect because when currents flow in the same direction, they do not repel each other. Choice C is incorrect because there is indeed a force present due to the interaction of magnetic fields, resulting in attraction between the wires.

2. What body of water does The Golden Gate Bridge cross?

Correct answer: A

Rationale: The Golden Gate Bridge crosses the entrance to San Francisco Bay, spanning the Golden Gate Strait. It does not cross the Pacific Ocean, Marin Strait, or Indian Ocean directly. The iconic bridge connects the city of San Francisco to Marin County in California. The Pacific Ocean is a vast body of water beyond the Golden Gate entrance, and Marin Strait is not a recognized geographical location. The Indian Ocean is located on a different continent and is not related to the Golden Gate Bridge's location.

3. If there are 128 ounces in 1 gallon, how many ounces are in 2.5 gallons?

Correct answer: B

Rationale: To find the total number of ounces in 2.5 gallons, multiply the number of gallons by the number of ounces per gallon: 2.5 gallons × 128 ounces/gallon = 320 ounces. The correct answer is 320 ounces. Choice C (400 ounces) is incorrect because multiplying 2.5 by 128 gives 320, not 400. Choice D (250 ounces) is also incorrect as it seems to be a miscalculation.

4. Which sentence is NOT GRAMMATICALLY CORRECT?

Correct answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).

5. Which of the following organelles is responsible for producing ATP in cells?

Correct answer: B

Rationale: The correct answer is 'Mitochondrion.' Mitochondria are known as the powerhouse of the cell and are responsible for producing ATP, the energy currency of the cell. The nucleus is responsible for storing genetic material and controlling cell activities, not for ATP production. Chloroplasts are found in plant cells and are responsible for photosynthesis, not ATP production. Lysosomes are involved in digestion and waste removal, not ATP production.
