In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
Antigens illicit the release of what in the body?, Context: The humoral (antibody) response is defined as the interaction between antibodies and antigens. Antibodies are specific proteins released from a certain class of immune cells known as B lymphocytes, while antigens are defined as anything that elicits the generation of antibodies ("anti"body "gen"erators). Immunology rests on an understanding of the properties of these two biological entities and the cellular response to both.

Ex Output:
antibodies

What did Darwin think about Wallace's theory, Context: Darwin was hard at work on his "big book" on Natural Selection, when on 18 June 1858 he received a parcel from Wallace, who stayed on the Maluku Islands (Ternate and Gilolo). It enclosed twenty pages describing an evolutionary mechanism, a response to Darwin's recent encouragement, with a request to send it on to Lyell if Darwin thought it worthwhile. The mechanism was similar to Darwin's own theory. Darwin wrote to Lyell that "your words have come true with a vengeance, ... forestalled" and he would "of course, at once write and offer to send [it] to any journal" that Wallace chose, adding that "all my originality, whatever it may amount to, will be smashed". Lyell and Hooker agreed that a joint publication putting together Wallace's pages with extracts from Darwin's 1844 Essay and his 1857 letter to Gray should be presented at the Linnean Society, and on 1 July 1858, the papers entitled On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, by Wallace and Darwin respectively, were read out but drew little reaction. While Darwin considered Wallace's idea to be identical to his concept of natural selection, historians have pointed out differences. Darwin described natural selection as being analogous to the artificial selection practised by animal breeders, and emphasised competition between individuals; Wallace drew no comparison to selective breeding, and focused on ecological pressures that kept different varieties adapted to local conditions. Some historians have suggested that Wallace was actually discussing group selection rather than selection acting on individual variation.

Ex Output:
On the Tendency of Species to form Varieties


Ex Input:
When did True Love take place?, Context: Bronx native Nancy Savoca's 1989 comedy, True Love, explores two Italian-American Bronx sweethearts in the days before their wedding. The film, which debuted Annabella Sciorra and Ron Eldard as the betrothed couple, won the Grand Jury Prize at that year's Sundance Film Festival. The CBS television sitcom Becker, 1998–2004, was more ambiguous. The show starred Ted Danson as Dr. John Becker, a doctor who operated a small practice and was constantly annoyed by his patients, co-workers, friends, and practically everything and everybody else in his world. It showed his everyday life as a doctor working in a small clinic in the Bronx.

Ex Output:
in the days before their wedding
