QUES: In modern color theory, also known as the RGB color model, red, green and blue are additive primary colors. Red, green and blue light combined together makes white light, and these three colors, combined in different mixtures, can produce nearly any other color. This is the principle that is used to make all of the colors on your computer screen and your television. For example, purple on a computer screen is made by a similar formula to used by Cennino Cennini in the Renaissance to make violet, but using additive colors and light instead of pigment: it is created by combining red and blue light at equal intensity on a black screen. Violet is made on a computer screen in a similar way, but with a greater amount of blue light and less red light.
Which era did Cennino Cennini actively paint in?

ANS: the Renaissance

QUES: The books written later in the Abbasid period in Iran are more anti Umayyad. Iran was Sunni at the time. There was much anti Arab feeling in Iran after the fall of the Persian empire. This anti Arab feeling also influenced the books on Islamic history. Al-Tabri was also written in Iran during that period. Al-Tabri was a huge collection including all the text that he could find, from all the sources. It was a collection preserving everything for future generations to codify and for future generations to judge if it was true or false.
In the later Abbasid era, what branch of Islam did Iran adhere to?

ANS: Sunni

QUES: Studies of nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all material excreted and eliminated from the body (in urine and feces). Comparing the food to the waste can help determine the specific compounds and elements absorbed and metabolized in the body. The effects of nutrients may only be discernible over an extended period, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of animal nutrition is still slowly evolving.
Other than time consuming, what else are nutritional studies due to their length and variable count?

ANS:
expensive
