Please solve this question 6. During the first few minutes after the BigBang, the universe was opaque. Light couldnot go through it. Why?4. How does the Cosmic MicrowaveBackground Radiation (CMBR) mark animportant milestone in the early history ofthe universe?A. All the photons were being absorbed.A. The CMBR originated as the first visiblelight. It marks time when the universetransitioned from opaque to transparent.B. There was nothing to produce photons.C. The photons were attracted to otherparticles.B. The CMBR originated from the initialforce that triggered the Big Bang. It is theremnant energy from the previous universe.D. The mix of particles was so dense thatphotons could not get through.7. What determined the temperature, density,C. The CMBR originated when the firstmassive stars in the universe beganexploding as supernovas shortly after theBig Bang.and ratio of hydrogen to helium of theuniverse soon after the Big Bang?A. the rate at which the universe expandedD. The CMBR originated as the firstB. the rate of nuclear fusion in the first starsmicrowave radiation. It marks the time theuniverse first became energic enough toproduce microwaves.C. the density of the material the universe wasexpanding intoD. the timing of the transition from an opaqueto a transparent universe5. When did the universe begin?A. 1 billion years agoB. 10 million years agoC. 14 billion years agoD. 50 billion years agoRead each statement. Write your answer on the lines.8. A classmate named Brandon is arguing that if the universe had expanded more slowly than it did, thetransition from an opaque to a transparent universe would have happened sooner than it actually did.How would you explain to Brandon, using the formation of the first elements in the universe, that he iswrong?

The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that permeates…
