Q1. What is the primary evidence for the existence of dark matter?

A. The expansion of the universe
B. Gravitational lensing and galaxy rotation curves ✓
C. The cosmic microwave background radiation
D. The Big Bang theory

Why: Gravitational lensing and galaxy rotation curves provide the primary observational evidence for dark matter, as they indicate the presence of unseen mass affecting visible matter.

Q2. Which of the following is a candidate for dark matter?

A. Protons
B. WIMPs ✓
C. Neutrinos
D. Photons

Why: WIMPs (Weakly Interacting Massive Particles) are one of the leading candidates for dark matter due to their properties that match the observed effects of dark matter.

Q3. What is the estimated percentage of the universe's total mass-energy content that is composed of dark matter?

A. 5%
B. 27% ✓
C. 68%
D. 95%

Why: Dark matter is estimated to make up about 27% of the universe's total mass-energy content, while dark energy accounts for approximately 68%.

Q4. Which of the following interactions is expected for dark matter particles?

A. Strong nuclear force
B. Electromagnetic force
C. Weak nuclear force
D. No significant interaction with ordinary matter ✓

Why: Dark matter is expected to have no significant interaction with ordinary matter, which is why it is difficult to detect directly.

Q5. What is the role of dark matter in the formation of galaxies?

A. It provides the energy for star formation
B. It acts as a gravitational scaffold for visible matter to clump together ✓
C. It emits light that helps form galaxies
D. It prevents galaxies from forming

Why: Dark matter provides the gravitational scaffold that allows visible matter to clump together and form galaxies, as its gravitational influence is necessary for the structure of the universe.
