Problem: Pharmaceutical industry:

Prior to the second world war, birth control was prohibited in many countries, and in the United States even the discussion of contraceptive methods sometimes led to prosecution under Comstock laws. The history of the development of oral contraceptives is thus closely tied to the birth control movement and the efforts of activists Margaret Sanger, Mary Dennett, and Emma Goldman. Based on fundamental research performed by Gregory Pincus and synthetic methods for progesterone developed by Carl Djerassi at Syntex and by Frank Colton at G.D. Searle & Co., the first oral contraceptive, Enovid, was developed by E.D. Searle and Co. and approved by the FDA in 1960. The original formulation incorporated vastly excessive doses of hormones, and caused severe side effects. Nonetheless, by 1962, 1.2 million American women were on the pill, and by 1965 the number had increased to 6.5 million. The availability of a convenient form of temporary contraceptive led to dramatic changes in social mores including expanding the range of lifestyle options available to women, reducing the reliance of women on men for contraceptive practice, encouraging the delay of marriage, and increasing pre-marital co-habitation.

In 1965, how many women were on the birth control pill?
---
A: 6.5 million

Problem: Hyderabad:

Hyderabad (i/hadrbd/ HY-dr--bad; often /hadrbd/) is the capital of the southern Indian state of Telangana and de jure capital of Andhra Pradesh.[A] Occupying 650 square kilometres (250 sq mi) along the banks of the Musi River, it has a population of about 6.7 million and a metropolitan population of about 7.75 million, making it the fourth most populous city and sixth most populous urban agglomeration in India. At an average altitude of 542 metres (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including Hussain Sagarpredating the city's foundingnorth of the city centre.

What is the population of Hyderabad?

Problem: Religion in ancient Rome:

While the new plebeian nobility made social, political and religious inroads on traditionally patrician preserves, their electorate maintained their distinctive political traditions and religious cults. During the Punic crisis, popular cult to Dionysus emerged from southern Italy; Dionysus was equated with Father Liber, the inventor of plebeian augury and personification of plebeian freedoms, and with Roman Bacchus. Official consternation at these enthusiastic, unofficial Bacchanalia cults was expressed as moral outrage at their supposed subversion, and was followed by ferocious suppression. Much later, a statue of Marsyas, the silen of Dionysus flayed by Apollo, became a focus of brief symbolic resistance to Augustus' censorship. Augustus himself claimed the patronage of Venus and Apollo; but his settlement appealed to all classes. Where loyalty was implicit, no divine hierarchy need be politically enforced; Liber's festival continued.

During what time did the Dionysus cult become popular?
---
A: Punic crisis

Problem: Textual criticism:

When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).

Different documents that represent the same original text are called what?
---
A:
witnesses
