Problem: Please answer a question about the following article about Armenians:
Art historian Hravard Hakobyan notes that "Artsakh carpets occupy a special place in the history of Armenian carpet-making." Common themes and patterns found on Armenian carpets were the depiction of dragons and eagles. They were diverse in style, rich in color and ornamental motifs, and were even separated in categories depending on what sort of animals were depicted on them, such as artsvagorgs (eagle-carpets), vishapagorgs (dragon-carpets) and otsagorgs (serpent-carpets). The rug mentioned in the Kaptavan inscriptions is composed of three arches, "covered with vegatative ornaments", and bears an artistic resemblance to the illuminated manuscripts produced in Artsakh.
What are vishapagorgs?
A: dragon-carpets
Problem: Please answer a question about the following article about Virgil:
The tradition holds that Virgil was born in the village of Andes, near Mantua in Cisalpine Gaul. Analysis of his name has led to beliefs that he descended from earlier Roman colonists. Modern speculation ultimately is not supported by narrative evidence either from his own writings or his later biographers. Macrobius says that Virgil's father was of a humble background; however, scholars generally believe that Virgil was from an equestrian landowning family which could afford to give him an education. He attended schools in Cremona, Mediolanum, Rome and Naples. After considering briefly a career in rhetoric and law, the young Virgil turned his talents to poetry.
Which type of family do scholars generally believe Virgil belonged to?
A: equestrian landowning
Problem: Please answer a question about the following article about Film speed:
The Weston Cadet (model 852 introduced in 1949), Direct Reading (model 853 introduced 1954) and Master III (models 737 and S141.3 introduced in 1956) were the first in their line of exposure meters to switch and utilize the meanwhile established ASA scale instead. Other models used the original Weston scale up until ca. 1955. The company continued to publish Weston film ratings after 1955, but while their recommended values often differed slightly from the ASA film speeds found on film boxes, these newer Weston values were based on the ASA system and had to be converted for use with older Weston meters by subtracting 1/3 exposure stop as per Weston's recommendation. Vice versa, "old" Weston film speed ratings could be converted into "new" Westons and the ASA scale by adding the same amount, that is, a film rating of 100 Weston (up to 1955) corresponded with 125 ASA (as per ASA PH2.5-1954 and before). This conversion was not necessary on Weston meters manufactured and Weston film ratings published since 1956 due to their inherent use of the ASA system; however the changes of the ASA PH2.5-1960 revision may be taken into account when comparing with newer ASA or ISO values.
How were Weston values changed to ASA values?
A: by subtracting 1/3 exposure stop
Problem: Please answer a question about the following article about Alps:
The first British Mont Blanc ascent was in 1788; the first female ascent in 1819. By the mid-1850s Swiss mountaineers had ascended most of the peaks and were eagerly sought as mountain guides. Edward Whymper reached the top of the Matterhorn in 1865 (after seven attempts), and in 1938 the last of the six great north faces of the Alps was climbed with the first ascent of the Eiger Nordwand (north face of the Eiger).
What year did Edward Whymper reach the top of the Matterhorn?
A:
1865
