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: How bad were Nasser's heart attacks?, Context: Nasser had few personal vices other than chain smoking. He maintained 18-hour workdays and rarely took time off for vacations. The combination of smoking and working long hours contributed to his poor health. He was diagnosed with diabetes in the early 1960s and by the time of his death in 1970, he also had arteriosclerosis, heart disease, and high blood pressure. He suffered two major heart attacks (in 1966 and 1969), and was on bed rest for six weeks after the second episode. State media reported that Nasser's absence from the public view at that time was a result of influenza.
Example Output: major heart attacks

Example Input: What was Cork City formerly surrounded by?, Context: The city's charter was granted by Prince John, as Lord of Ireland, in 1185. The city was once fully walled, and some wall sections and gates remain today. For much of the Middle Ages, Cork city was an outpost of Old English culture in the midst of a predominantly hostile Gaelic countryside and cut off from the English government in the Pale around Dublin. Neighbouring Gaelic and Hiberno-Norman lords extorted "Black Rent" from the citizens to keep them from attacking the city. The present extent of the city has exceeded the medieval boundaries of the Barony of Cork City; it now takes in much of the neighbouring Barony of Cork. Together, these baronies are located between the Barony of Barrymore to the east, Muskerry East to the west and Kerrycurrihy to the south.
Example Output: wall

Example Input: Which of the following is not a form of taking in sensory information: visual acuity, patterns or tactile acuity?, Context: Many insects possess very sensitive and, or specialized organs of perception. Some insects such as bees can perceive ultraviolet wavelengths, or detect polarized light, while the antennae of male moths can detect the pheromones of female moths over distances of many kilometers. The yellow paper wasp (Polistes versicolor) is known for its wagging movements as a form of communication within the colony; it can waggle with a frequency of 10.62.1 Hz (n=190). These wagging movements can signal the arrival of new material into the nest and aggression between workers can be used to stimulate others to increase foraging expeditions. There is a pronounced tendency for there to be a trade-off between visual acuity and chemical or tactile acuity, such that most insects with well-developed eyes have reduced or simple antennae, and vice versa. There are a variety of different mechanisms by which insects perceive sound, while the patterns are not universal, insects can generally hear sound if they can produce it. Different insect species can have varying hearing, though most insects can hear only a narrow range of frequencies related to the frequency of the sounds they can produce. Mosquitoes have been found to hear up to 2 kHz., and some grasshoppers can hear up to 50 kHz. Certain predatory and parasitic insects can detect the characteristic sounds made by their prey or hosts, respectively. For instance, some nocturnal moths can perceive the ultrasonic emissions of bats, which helps them avoid predation.:8794 Insects that feed on blood have special sensory structures that can detect infrared emissions, and use them to home in on their hosts.
Example Output:
patterns
