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

Input: Consider Input: What did the supercapacitors improve?, Context: Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".

Output: electrolytic capacitor


Input: Consider Input: what is the second to last profession mentioned?, Context: Like the rest of India, Hyderabad has a large informal economy that employs 30% of the labour force.:71 According to a survey published in 2007, it had 40–50,000 street vendors, and their numbers were increasing.:9 Among the street vendors, 84% are male and 16% female,:12 and four fifths are "stationary vendors" operating from a fixed pitch, often with their own stall.:15–16 Most are financed through personal savings; only 8% borrow from moneylenders.:19 Vendor earnings vary from ₹50 (74¢ US) to ₹800 (US$12) per day.:25 Other unorganised economic sectors include dairy, poultry farming, brick manufacturing, casual labour and domestic help. Those involved in the informal economy constitute a major portion of urban poor.:71

Output: casual labour


Input: Consider Input: What exactly do motor systems do to create body movements, such as lifting a cup or walking?, Context: Motor systems are areas of the brain that are directly or indirectly involved in producing body movements, that is, in activating muscles. Except for the muscles that control the eye, which are driven by nuclei in the midbrain, all the voluntary muscles in the body are directly innervated by motor neurons in the spinal cord and hindbrain. Spinal motor neurons are controlled both by neural circuits intrinsic to the spinal cord, and by inputs that descend from the brain. The intrinsic spinal circuits implement many reflex responses, and contain pattern generators for rhythmic movements such as walking or swimming. The descending connections from the brain allow for more sophisticated control.
Output: activating muscles
