Problem: Kermes is also mentioned in the Bible. In the Book of Exodus, God instructs Moses to have the Israelites bring him an offering including cloth "of blue, and purple, and scarlet." The term used for scarlet in the 4th century Latin Vulgate version of the Bible passage is coccumque bis tinctum, meaning "colored twice with coccus." Coccus, from the ancient Greek Kokkos, means a tiny grain and is the term that was used in ancient times for the Kermes vermilio insect used to make the Kermes dye. This was also the origin of the expression "dyed in the grain."
Who did Moses instruct to bring him cloth?

Context and question: His best known wife was Jovanka Broz. Tito was just shy of his 59th birthday, while she was 27, when they finally married in April 1952, with state security chief Aleksandar Ranković as the best man. Their eventual marriage came about somewhat unexpectedly since Tito actually rejected her some years earlier when his confidante Ivan Krajacic brought her in originally. At that time, she was in her early 20s and Tito, objecting to her energetic personality, opted for the more mature opera singer Zinka Kunc instead. Not one to be discouraged easily, Jovanka continued working at Beli Dvor, where she managed the staff and eventually got another chance after Tito's strange relationship with Zinka failed. Since Jovanka was the only female companion he married while in power, she also went down in history as Yugoslavia's first lady. Their relationship was not a happy one, however. It had gone through many, often public, ups and downs with episodes of infidelities and even allegations of preparation for a coup d'état by the latter pair. Certain unofficial reports suggest Tito and Jovanka even formally divorced in the late 1970s, shortly before his death. However, during Tito's funeral she was officially present as his wife, and later claimed rights for inheritance. The couple did not have any children.
How old was Jovanka Broz when she married Tito?
Answer: 27

Question: Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.
Is there an answer to this question: What technology allows infrared thermal imaging cameras to observe people or animals without being detected?

Answer:
unanswerable
