Question: The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant. With the arrival of cochineal, they had a third, carmine, which made a very fine crimson, though it had a tendency to change color if not used carefully. It was used by almost all the great painters of the 15th and 16th centuries, including Rembrandt, Vermeer, Rubens, Anthony van Dyck, Diego Velazquez and Tintoretto. Later it was used by Thomas Gainsborough, Seurat and J.M.W. Turner.
Is there an answer to this question: What was madder lake made from?

Answer: rubia tinctorum plant

Question: The 1977 Knesset elections marked a major turning point in Israeli political history as Menachem Begin's Likud party took control from the Labor Party. Later that year, Egyptian President Anwar El Sadat made a trip to Israel and spoke before the Knesset in what was the first recognition of Israel by an Arab head of state. In the two years that followed, Sadat and Begin signed the Camp David Accords (1978) and the IsraelEgypt Peace Treaty (1979). In return, Israel withdrew from the Sinai Peninsula, which Israel had captured during the Six-Day War in 1967, and agreed to enter negotiations over an autonomy for Palestinians in the West Bank and the Gaza Strip.
Is there an answer to this question: Where did Anwar El Sadat make a trip to?

Question: The Macintosh project was begun in 1979 by Jef Raskin, an Apple employee who envisioned an easy-to-use, low-cost computer for the average consumer. He wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc., the audio equipment manufacturer. Steve Jobs requested that McIntosh Laboratory give Apple a release for the name with its changed spelling so that Apple could use it, but the request was denied, forcing Apple to eventually buy the rights to use the name. (A 1984 Byte Magazine article suggested Apple changed the spelling only after "early users" misspelled "McIntosh". However, Jef Raskin had adopted the Macintosh spelling by 1981, when the Macintosh computer was still a single prototype machine in the lab. This explanation further clashes with the first explanation given above that the change was made for "legal reasons.")
Is there an answer to this question: What did Jef Raskin envision for a computer to be for an average business?
