Problem: Extract the answer to the question from the following context. Question: What brings out our emotions? Context: Emotions have been described by some theorists as discrete and consistent responses to internal or external events which have a particular significance for the organism. Emotions are brief in duration and consist of a coordinated set of responses, which may include verbal, physiological, behavioural, and neural mechanisms. Psychotherapist Michael C. Graham describes all emotions as existing on a continuum of intensity. Thus fear might range from mild concern to terror or shame might range from simple embarrassment to toxic shame. Emotions have also been described as biologically given and a result of evolution because they provided good solutions to ancient and recurring problems that faced our ancestors. Moods are feelings that tend to be less intense than emotions and that often lack a contextual stimulus.

A: responses to internal or external events which have a particular significance for the organism

Problem: Extract the answer to the question from the following context. Question: What is the smallest amount of money available? Context: Currently printed denominations are $1, $2, $5, $10, $20, $50, and $100. Notes above the $100 denomination stopped being printed in 1946 and were officially withdrawn from circulation in 1969. These notes were used primarily in inter-bank transactions or by organized crime; it was the latter usage that prompted President Richard Nixon to issue an executive order in 1969 halting their use. With the advent of electronic banking, they became less necessary. Notes in denominations of $500, $1,000, $5,000, $10,000 and $100,000 were all produced at one time; see large denomination bills in U.S. currency for details. These notes are now collectors' items and are worth more than their face value to collectors.

A: $1

Problem: Extract the answer to the question from the following context. Question: Who is the third-most represented party in Parliament Context: London is the seat of the Government of the United Kingdom. Many government departments are based close to the Palace of Westminster, particularly along Whitehall, including the Prime Minister's residence at 10 Downing Street. The British Parliament is often referred to as the "Mother of Parliaments" (although this sobriquet was first applied to England itself by John Bright) because it has been the model for most other parliamentary systems. There are 73 Members of Parliament (MPs) from London, who correspond to local parliamentary constituencies in the national Parliament. As of May 2015, 45 are from the Labour Party, 27 are Conservatives, and one is a Liberal Democrat.

A: Liberal Democrat

Problem: Extract the answer to the question from the following context. Question: How have the structures changed to survive bitter weather? Context: About 1150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming. Some of these species are cryptoendoliths as a result of evolution under extreme conditions, and have significantly contributed to shaping the impressive rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. The apparently simple morphology, scarcely differentiated structures, metabolic systems and enzymes still active at very low temperatures, and reduced life cycles shown by such fungi make them particularly suited to harsh environments such as the McMurdo Dry Valleys. In particular, their thick-walled and strongly melanized cells make them resistant to UV light. Those features can also be observed in algae and cyanobacteria, suggesting that these are adaptations to the conditions prevailing in Antarctica. This has led to speculation that, if life ever occurred on Mars, it might have looked similar to Antarctic fungi such as Cryomyces minteri. Some of these fungi are also apparently endemic to Antarctica. Endemic Antarctic fungi also include certain dung-inhabiting species which have had to evolve in response to the double challenge of extreme cold while growing on dung, and the need to survive passage through the gut of warm-blooded animals.

A:
