Input: Read this: Land Forces during this period also deployed in support of peacekeeping operations within United Nations sanctioned conflicts. The nature of the Canadian Forces has continued to evolve. They have been deployed in Afghanistan until 2011, under the NATO-led United Nations International Security Assistance Force (ISAF), at the request of the Government of Afghanistan.
Question: What forces were sent out in support of peacekeeping?

Output: Land Forces


Input: Read this: The climate of Saint Helena is tropical, marine and mild, tempered by the Benguela Current and trade winds that blow almost continuously. The climate varies noticeably across the island. Temperatures in Jamestown, on the north leeward shore, range between 21–28 °C (70–82 °F) in the summer (January to April) and 17–24 °C (63–75 °F) during the remainder of the year. The temperatures in the central areas are, on average, 5–6 °C (9.0–10.8 °F) lower. Jamestown also has a very low annual rainfall, while 750–1,000 mm (30–39 in) falls per year on the higher ground and the south coast, where it is also noticeably cloudier. There are weather recording stations in the Longwood and Blue Hill districts.
Question: What current affects the environment of Saint Helena?

Output: Benguela Current


Input: Read this: From an evolutionary-biological perspective, the function of the brain is to provide coherent control over the actions of an animal. A centralized brain allows groups of muscles to be co-activated in complex patterns; it also allows stimuli impinging on one part of the body to evoke responses in other parts, and it can prevent different parts of the body from acting at cross-purposes to each other.
Question: The function of the brain from an evolutionary-biological thought is what?

Output: provide coherent control over the actions of an animal


Input: Read this: Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.
Question: What issue can complicate electric railway service?

Output:
different supply voltages and frequencies,
