Problem: Film speed:

The Recommended Exposure Index (REI) technique, new in the 2006 version of the standard, allows the manufacturer to specify a camera model's EI choices arbitrarily. The choices are based solely on the manufacturer's opinion of what EI values produce well-exposed sRGB images at the various sensor sensitivity settings. This is the only technique available under the standard for output formats that are not in the sRGB color space. This is also the only technique available under the standard when multi-zone metering (also called pattern metering) is used.

What standardized EI choices?

A: unanswerable

Problem: Christian:

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: , ca 988 AD). People of that time used to denote themselves Christians (, ) and Russians (). Both terms had strong Christian connotations.[citation needed] It is also interesting that in time the term "" acquired the meaning "peasants of Christian faith" and later "peasants" (the main part of the population of the region), while the term "" retained its religious meaning and the term "" 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" ( - Orthodox faith) or "Russian faith" ( ) from earliest times became almost as known as the original "Christian faith" (, ). Also in some contexts the term "cossack" (, - free man by the will of God) was used[by whom?] to denote "free" Christians of steppe origin and Russian language.

A: Armenia

Problem: Adolescence:

The appearance of more systematic, abstract thinking is another notable aspect of cognitive development during adolescence. For example, adolescents find it easier than children to comprehend the sorts of higher-order abstract logic inherent in puns, proverbs, metaphors, and analogies. Their increased facility permits them to appreciate the ways in which language can be used to convey multiple messages, such as satire, metaphor, and sarcasm. (Children younger than age nine often cannot comprehend sarcasm at all.) This also permits the application of advanced reasoning and logical processes to social and ideological matters such as interpersonal relationships, politics, philosophy, religion, morality, friendship, faith, democracy, fairness, and honesty.
