Problem: Extract the answer to the question from the following context. Question: The bacteria that were found in an environment with minimal nutrients had which type of shape when cut at a right angle to an axis? Context: Most bacterial species are either spherical, called cocci (sing. coccus, from Greek kokkos, grain, seed), or rod-shaped, called bacilli (sing. bacillus, from Latin baculus, stick). Elongation is associated with swimming. Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of species even have tetrahedral or cuboidal shapes. More recently, some bacteria were discovered deep under Earth's crust that grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology may give these bacteria an advantage in nutrient-poor environments. This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.

Problem: Extract the answer to the question from the following context. Question: What type of job is the most prolific for students nowadays? Context: While full-time work hinders schooling, empirical evidence is varied on the relationship between part-time work and school. Sometimes even part-time work may hinder school attendance or performance. On the other hand, many poor children work for resources to attend school. Children who are not doing well at school sometimes seek more satisfactory experience in work. Good relations with a supervisor at work can provide relief from tensions that children feel at school and home. In the modern world, school education has become so central to society that schoolwork has become the dominant work for most children, often replacing participation in productive work. If school curricula or quality do not provide children with appropriate skills for available jobs or if children do nor have the aptitude for schoolwork, school may impede the learning of skills, such as agriculture, which will become necessary for future livelihood.

A: schoolwork has become the dominant work for most children

Problem: Extract the answer to the question from the following context. Question: Which of the following is not a possible attack vector: Bluetooth, cell phone network, or passwords? Context: Desktop computers and laptops are commonly infected with malware either to gather passwords or financial account information, or to construct a botnet to attack another target. Smart phones, tablet computers, smart watches, and other mobile devices such as Quantified Self devices like activity trackers have also become targets and many of these have sensors such as cameras, microphones, GPS receivers, compasses, and accelerometers which could be exploited, and may collect personal information, including sensitive health information. Wifi, Bluetooth, and cell phone network on any of these devices could be used as attack vectors, and sensors might be remotely activated after a successful breach.

A: passwords

Problem: Extract the answer to the question from the following context. Question: What was Sam's educational background? Context: During the period from 1993 to 2011, FBI agents fired their weapons on 289 occasions; FBI internal reviews found the shots justified in all but 5 cases, in none of the 5 cases were people wounded. Samuel Walker, a professor of criminal justice at the University of Nebraska Omaha said the number of shots found to be unjustified was "suspiciously low." In the same time period, the FBI wounded 150 people, 70 of whom died; the FBI found all 150 shootings to be justified. Likewise, during the period from 2011 to the present, all shootings by FBI agents have been found to be justified by internal investigation. In a 2002 case in Maryland, an innocent man was shot, and later paid $1.3 million by the FBI after agents mistook him for a bank robber; the internal investigation found that the shooting was justified, based on the man's actions.

A:
