the purpose of building a prototype?
A. A prototype is an early example of technology. It allows scientists to test their idea and then make adjustments based on their observations
B. Prototypes give scientists a chance to build their ideas and show their peers. Scientists can then talk about how their prototype is the best version.
C. Warehouses are able to build prototypes in bulk. Once the prototypes are built, they are ready to be sold in stores.
D. Prototypes allow scientists to compete to build the best version of technology.
A. A prototype is an early example of technology. It allows scientists to test their idea and then make adjustments based on their observations

One of the closest stars to Earth is Alpha Centauri A. It is larger than the Sun, yet it appears much less bright. Why?
a. The smaller a star is, the more concentrated its energy is, so it appears brighter.
b.The difference in brightness is due to the difference in relative distance.
c. Dust in the Earth’s atmosphere absorbs the light of all the stars we see.
d. As stars get older, the amount of light they give off decreases.
b.The difference in brightness is due to the difference in relative distance.
