Problem: Transistor:

Although several companies each produce over a billion individually packaged (known as discrete) transistors every year, the vast majority of transistors are now produced in integrated circuits (often shortened to IC, microchips or simply chips), along with diodes, resistors, capacitors and other electronic components, to produce complete electronic circuits. A logic gate consists of up to about twenty transistors whereas an advanced microprocessor, as of 2009, can use as many as 3 billion transistors (MOSFETs). "About 60 million transistors were built in 2002… for [each] man, woman, and child on Earth."

How many men, women, and children are on Earth?

Problem: In an attempt to provide general descriptions that may facilitate the job of law enforcement officers seeking to apprehend suspects, the United States FBI employs the term "race" to summarize the general appearance (skin color, hair texture, eye shape, and other such easily noticed characteristics) of individuals whom they are attempting to apprehend. From the perspective of law enforcement officers, it is generally more important to arrive at a description that will readily suggest the general appearance of an individual than to make a scientifically valid categorization by DNA or other such means. Thus, in addition to assigning a wanted individual to a racial category, such a description will include: height, weight, eye color, scars and other distinguishing characteristics.
What is more important for law enforcement in categorizing instead of DNA?

Answer: arrive at a description

The region of modern Eastern Europe and Central Eurasia (Russia, Ukraine and other countries of the ex-USSR) have a long history of Christianity and Christian communities on its lands. In ancient times, in the first centuries after the birth of Christ, when this region was called[by whom?] Scythia - Christians already lived there. Later the region saw the first states to adopt Christianity officially - initially in Armenia (301 AD) and in Georgia (337 AD), later in the Great Russian Principality (Kyivan Rus, Russian: Великое княжество Русское, ca 988 AD). People of that time used to denote themselves Christians (христиане, крестьяне) and Russians (русские). Both terms had strong Christian connotations.[citation needed] It is also interesting that in time the term "крестьяне" acquired the meaning "peasants of Christian faith" and later "peasants" (the main part of the population of the region), while the term "христиане" retained its religious meaning and the term "русские" began to mean representatives of the heterogeneous Russian nation formed on the basis of common Christian faith and language,[citation needed] which strongly influenced the history and development of the region. In the region the "Pravoslav faith" (православная вера - Orthodox faith) or "Russian faith" (русская вера) from earliest times became almost as known as the original "Christian faith" (христианская, крестьянская вера). Also in some contexts the term "cossack" (козак, казак - free man by the will of God) was used[by whom?] to denote "free" Christians of steppe origin and Russian language.
Which term came to be known as meaning representatives of the heterogeneous Christian nation?
A: unanswerable


Context and question: Before World War II, Guam and three other territories – American Samoa, Hawaii, and the Philippines – were the only American jurisdictions in the Pacific Ocean. On December 7, 1941, hours after the attack on Pearl Harbor, Guam was captured by the Japanese, and was occupied for thirty months. During the occupation, Guamanians were subjected to culture alignment, forced labor, beheadings, rape, and torture. Guam endured hostilities when American forces recaptured the island on July 21, 1944; Liberation Day commemorates the victory. Since the 1960s, the economy is supported by two industries: tourism and the United States Armed Forces.
In what year did the US acquire American Samoa?
Answer: unanswerable


Question: In the later Imperial era, the burial and commemorative practises of Christian and non-Christians overlapped. Tombs were shared by Christian and non-Christian family members, and the traditional funeral rites and feast of novemdialis found a part-match in the Christian Constitutio Apostolica. The customary offers of wine and food to the dead continued; St Augustine (following St Ambrose) feared that this invited the "drunken" practices of Parentalia but commended funeral feasts as a Christian opportunity to give alms of food to the poor. Christians attended Parentalia and its accompanying Feralia and Caristia in sufficient numbers for the Council of Tours to forbid them in AD 567. Other funerary and commemorative practices were very different. Traditional Roman practice spurned the corpse as a ritual pollution; inscriptions noted the day of birth and duration of life. The Christian Church fostered the veneration of saintly relics, and inscriptions marked the day of death as a transition to "new life".
Is there an answer to this question: When was Christian attendance at Parentalia become forbidden by the Christians?

Answer: AD 567

Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.
What is the term that uses the infrared spectrum that is radiated by hot bodies?
A:
unanswerable
