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

Example Input: Which is larger, cliques or crowds?, Context: Adolescents tend to associate with "cliques" on a small scale and "crowds" on a larger scale. During early adolescence, adolescents often associate in cliques, exclusive, single-sex groups of peers with whom they are particularly close. Despite the common notion that cliques are an inherently negative influence, they may help adolescents become socially acclimated and form a stronger sense of identity. Within a clique of highly athletic male-peers, for example, the clique may create a stronger sense of fidelity and competition. Cliques also have become somewhat a "collective parent," i.e. telling the adolescents what to do and not to do. Towards late adolescence, cliques often merge into mixed-sex groups as teenagers begin romantically engaging with one another. These small friend groups then break down further as socialization becomes more couple-oriented. On a larger scale, adolescents often associate with crowds, groups of individuals who share a common interest or activity. Often, crowd identities may be the basis for stereotyping young people, such as jocks or nerds. In large, multi-ethnic high schools, there are often ethnically-determined crowds. While crowds are very influential during early and middle adolescence, they lose salience during high school as students identify more individually.
Example Output: crowds

Example Input: Polytechnics generally focused on what in the beginning?, Context: Polytechnics were tertiary education teaching institutions in England, Wales and Northern Ireland. Since 1970 UK Polytechnics operated under the binary system of education along with universities. Polytechnics offered diplomas and degrees (bachelor's, master's, PhD) validated at the national level by the UK Council for National Academic Awards CNAA. They particularly excelled in engineering and applied science degree courses similar to technological universities in the USA and continental Europe. The comparable institutions in Scotland were collectively referred to as Central Institutions. Britain's first Polytechnic, the Royal Polytechnic Institution later known as the Polytechnic of Central London (now the University of Westminster) was established in 1838 at Regent Street in London and its goal was to educate and popularize engineering and scientific knowledge and inventions in Victorian Britain "at little expense." The London Polytechnic led a mass movement to create numerous Polytechnic institutes across the UK in the late 19th Century. Most Polytechnic institutes were established at the centre of major metropolitan cities and their focus was on engineering, applied science and technology education.
Example Output: engineering, applied science and technology education

Example Input: What makes a dog able to pick up scents faster and further than a human could?, Context: Medical detection dogs are capable of detecting diseases by sniffing a person directly or samples of urine or other specimens. Dogs can detect odour in one part per trillion, as their brain's olfactory cortex is (relative to total brain size) 40 times larger than humans. Dogs may have as many as 300 million odour receptors in their nose, while humans may have only 5 million. Each dog is trained specifically for the detection of single disease from the blood glucose level indicative to diabetes to cancer. To train a cancer dog requires 6 months. A Labrador Retriever called Daisy has detected 551 cancer patients with an accuracy of 93 percent and received the Blue Cross (for pets) Medal for her life-saving skills.
Example Output:
Dogs may have as many as 300 million odour receptors in their nose, while humans may have only 5 million
