Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The evolution of the Greek sculpture can be observed in his depictions from the almost static formal Kouros type in early archaic period, to the representation of motion in a relative harmonious whole in late archaic period. In classical Greece the emphasis is not given to the illusive imaginative reality represented by the ideal forms, but to the analogies and the interaction of the members in the whole, a method created by Polykleitos. Finally Praxiteles seems to be released from any art and religious conformities, and his masterpieces are a mixture of naturalism with stylization.
In whose depictions can the evolution of Greek sculpture be observed?
A: Praxiteles

Context and question: The Warnerke Standard Sensitometer consisted of a frame holding an opaque screen with an array of typically 25 numbered, gradually pigmented squares brought into contact with the photographic plate during a timed test exposure under a phosphorescent tablet excited before by the light of a burning Magnesium ribbon. The speed of the emulsion was then expressed in 'degrees' Warnerke (sometimes seen as Warn. or W.) corresponding with the last number visible on the exposed plate after development and fixation. Each number represented an increase of 1/3 in speed, typical plate speeds were between 10 and 25 Warnerke at the time.
What were usual ranges of Warnerke speeds?
Answer: between 10 and 25 Warnerke

QUES: According to the First Epistle to the Corinthians (1 Cor. 15:4), Jesus was raised from the dead ("on the third day" counting the day of crucifixion as the first) and according to the canonical Gospels, appeared to his disciples on different occasions before ascending to heaven. The account given in Acts of the Apostles, which says Jesus remained with the apostles for forty days, appears to differ from the account in the Gospel of Luke, which makes no clear distinction between the events of Easter Sunday and the Ascension. However, most biblical scholars agree that St. Luke also wrote the Acts of the Apostles as a follow-up volume to his Gospel account, and the two works must be considered as a whole.

Who wrote both accounts of the Crucifixion and ascension?
What is the answer?
ANS:
St. Luke
