The claim that monsters are fake is based on the understanding that monsters do not exist in reality; they are fictional creatures created for stories, movies, and games intended for entertainment purposes. This aligns with option D as the correct answer.
Option Analysis:
Option A:
Incorrect because it suggests a lack of knowledge or certainty about the existence of monsters.
Option B:
Incorrect because it implies uncertainty, which does not match the established understanding that monsters are fictional.
Option C:
Incorrect as it contradicts the widely accepted notion that monsters do not exist in reality.
Option D:
Correct since monsters are recognized as fictional entities and not real beings.
2.
What can magnets do?
A) They can attract or repel each other.
B) They can stick to their poles.
C) They can feed animals.
D) None of above.
Show Answer
Explanations:
Magnets can attract or repel each other, which is a fundamental property of magnets. This means that opposite poles (north and south) attract each other, while like poles (north and north or south and south) repel each other.
Option Analysis:
Option A:
Correct. Magnets indeed have the ability to attract or repel each other based on their magnetic fields.
Option B:
Incorrect. Magnets do not stick to their poles; they interact with ferromagnetic materials like iron, nickel, and cobalt.
Option C:
Incorrect. Feeding animals is unrelated to the properties of magnets.
Option D:
Incorrect. Option A is correct.
3.
What is the function of air?
A) Breathe.

Option Analysis:
Option A:
Correct. Air's primary function is to facilitate breathing.
Option B:
Incorrect. "Mandi" means bath or washing, not related to air’s functions.
Option C:
Incorrect. Eating involves consuming food, unrelated to air’s role.
Option D:
Incorrect. Sleeping is a state of rest and does not directly involve the function of air.

Option Analysis:
Option A:
Pulling involves applying force to bring an object closer, not moving it away.
Option B:
Pushing oneself off the ground when jumping is more about using muscles to generate upward motion rather than pushing something away.
Option C:
Correct as explained above.
Option D:
Not applicable since option C is correct.
6.

8.
Energy= ..... to the speed of light squared
A) Gravity.
B) Mass.
C) Sandwich.
D) Lightning.
Show Answer
Explanations:
The correct answer is
B) Mass.
According to Einstein's famous equation, \( E = mc^2 \), energy (E) is equal to mass (m) times the speed of light squared (\( c^2 \)). This equation shows that a small amount of mass can be converted into a large amount of energy.
Option Analysis:
Option A:
Gravity does not directly relate to this equation. While gravity affects objects with mass, it is not the primary factor in the \( E = mc^2 \) relationship.
Option B:
Correct. Mass is a fundamental component of Einstein's mass-energy equivalence formula.
Option C:
A sandwich has no relation to this scientific concept and is unrelated to energy or mass in the context of \( E = mc^2 \).
Option D:
Lightning, while related to electrical energy, does not directly describe the relationship between energy and mass as stated by Einstein's equation.

Option A:
Incorrect. Spiders do not have two legs.
Option B:
Incorrect. Five is not the correct number of legs a spider has.
Option C:
Incorrect. Four does not match the actual number of legs on a spider.
Option D:
Correct. Spiders indeed have six legs, but this statement is incorrect as spiders actually have eight legs.
10.
Who wins in a tug of war game?
A) Whoever can make the strongest force.
B) Whoever can trip the other person.
C) Whoever just finished eating lunch.
D) None of above.
Show Answer

Option Analysis:
Option A:
Correct. Victory in tug of war is determined by who exerts a stronger force.
Option B:
Incorrect. Tripping an opponent does not determine the outcome; it's about pulling strength.
Option C:
Incorrect. Time of day or meal timing has no impact on tug of war results.
Option D:
Incorrect. At least one option is correct.
