Explanation:
The relationship between a main sequence star's b-v color value and luminosity is a direct relationship.
The Hipparcos satellite measures the distances between hundreds of thousands of stars. It measures the magnitude of each stars through two filters which are, a blue filter, yielding for B magnitude (for blue) and a greenish filter, yielding a V magnitude (for visual).
The difference between the B and V magnitude of star is (B-V) color , or sometimes just "color" in short. The wavelength of light where the star is related to the star's temperature, i.e., the hotter the star the more blue it is and the cooler the star the more red it is.

Answer:
freedom of speech, equality, freedom of press, and religious tolerance.
Not much is known about how the earliest civilizations adapted to their environments except through their cultural habits (i.e. religion, games, etc). The Mayans took advantage of the surrounding rain forests and developed a very heavy agricultural and farming civilization, focusing in the cultivation of maize, beans, squash, peppers, avocado, and other important foods. They created a system for tearing down the rain forest in order to make room for their fields and left the watering of the plants up to the gods as they believed that the sun and rain were entirely divine. The Aztecs, however, settled in a more marshy land that was difficult to cultivate. Instead, they relied on military power and strength to conquer other civilizations and steal their food to keep their civilization alive. They did a bit of growing on their own, but not to the same scale as the Mayans, developing water ways and canals to transport goods from conquered cities to their capital.
