What kind of small objects composes much of the universe?
- A.
  
  Atoms
- B.
  
  Dark matter
- C.
  
  Anti-matter
- D.
  
  Monster energy
Correct Answer
B. Dark matter

Explanation
Dark matter is the correct answer because it is a type of matter that is hypothesized to exist in the universe, although it cannot be directly observed. It does not emit, absorb, or reflect light, making it invisible. However, its presence can be inferred through its gravitational effects on visible matter. Dark matter is believed to make up a significant portion of the universe, playing a crucial role in the formation and evolution of galaxies and the large-scale structure of the cosmos.

Explanation
A decapod is a type of crustacean that has ten legs. Crabs are one of the most well-known examples of decapods. They have a hard exoskeleton, a pair of claws, and a body that is divided into a cephalothorax and an abdomen. They are commonly found in oceans, seas, and other bodies of water, and are known for their sideways walking and ability to regenerate lost limbs.

What's the shape of the Earth?
- A.
  
  Round
- B.
  
  Flat
- C.
  
  Has no shape
- D.
  
  Spheroid
Correct Answer
D. Spheroid

Explanation
The correct answer is "Spheroid". This is because the Earth is not a perfect sphere, but rather an oblate spheroid. It is slightly flattened at the poles and bulging at the equator due to its rotation. This shape is a result of the Earth's gravity pulling the mass towards the center, causing it to be compressed at the poles and expanded at the equator.

Which is a hypothetical string theory weightless particle?
- A.
  
  Graviton
- B.
  
  Earth Worm Jim
- C.
  
  Anti-matter
- D.
  
  Baryonic Matter
Correct Answer
A. Graviton

Explanation
A graviton is a hypothetical particle in string theory that is believed to be responsible for carrying the force of gravity. It is considered weightless because it does not have mass. While the other options mentioned are not weightless particles, the graviton fits the description of a hypothetical string theory particle that is weightless.

- A.
  
  Xenomorph
- B.
  
  Fish in trees
- C.
  
  Headcrab
- D.
  
  Grunt Helms
Correct Answer
B. Fish in trees

Explanation
The correct answer is "Fish in trees" because fish are aquatic creatures that are adapted to live in water, and trees are terrestrial structures that do not provide the necessary environment for fish to survive. Therefore, the idea of fish living in trees is not biologically possible and is purely fictional.
