  - context: 'A reusable launch system (RLS, or reusable launch vehicle, RLV) is a launch
      system which is capable of launching a payload into space more than once. This
      contrasts with expendable launch systems, where each launch vehicle is launched
      once and then discarded. No completely reusable orbital launch system has ever
      been created. Two partially reusable launch systems were developed, the Space
      Shuttle and Falcon 9. The Space Shuttle was partially reusable: the orbiter (which
      included the Space Shuttle main engines and the Orbital Maneuvering System engines),
      and the two solid rocket boosters were reused after several months of refitting
      work for each launch. The external tank was discarded after each flight.'

  - context: Robotics is an interdisciplinary branch of engineering and science that
      includes mechanical engineering, electrical engineering, computer science, and
      others. Robotics deals with the design, construction, operation, and use of robots,
      as well as computer systems for their control, sensory feedback, and information
      processing. These technologies are used to develop machines that can substitute
      for humans. Robots can be used in any situation and for any purpose, but today
      many are used in dangerous environments (including bomb detection and de-activation),
      manufacturing processes, or where humans cannot survive. Robots can take on any
      form but some are made to resemble humans in appearance. This is said to help
      in the acceptance of a robot in certain replicative behaviors usually performed
      by people. Such robots attempt to replicate walking, lifting, speech, cognition,
      and basically anything a human can do.

  - context: In the first quarter, the Bears drew first blood as kicker Robbie Gould
      nailed a 22-yard field goal for the only score of the period. In the second quarter,
      the Bears increased their lead with Gould nailing a 42-yard field goal. They increased
      their lead with Cutler firing a 7-yard TD pass to tight end Greg Olsen. The Bears
      then closed out the first half with Gould's 41-yard field goal. In the third quarter,
      the Vikes started to rally with running back Adrian Peterson's 1-yard touchdown
      run (with the extra point attempt blocked). The Bears increased their lead over
      the Vikings with Cutler's 2-yard TD pass to tight end Desmond Clark. The Vikings
      then closed out the quarter with quarterback Brett Favre firing a 6-yard TD pass
      to tight end Visanthe Shiancoe. An exciting fourth quarter ensued. The Vikings
      started out the quarter's scoring with kicker Ryan Longwell's 41-yard field goal,
      along with Adrian Peterson's second 1-yard TD run. The Bears then responded with
      Cutler firing a 20-yard TD pass to wide receiver Earl Bennett. The Vikings then
      completed the remarkable comeback with Favre finding wide receiver Sidney Rice
      on a 6-yard TD pass on 4th-and-goal with 15 seconds left in regulation. The Bears
      then took a knee to force overtime. In overtime, the Bears won the toss and marched
      down the field, stopping at the 35-yard line. However, the potential game-winning
      45-yard field goal attempt by Gould went wide right, giving the Vikings a chance
      to win. After an exchange of punts, the Vikings had the ball at the 26-yard line
      with 11 minutes left in the period. On the first play of scrimmage, Favre fired
      a screen pass to Peterson who caught it and went 16 yards, before being confronted
      by Hunter Hillenmeyer, who caused Peterson to fumble the ball, which was then
      recovered by Bears' linebacker Nick Roach. The Bears then won on Jay Cutler's
      game-winning 39-yard TD pass to wide receiver Devin Aromashodu. With the loss,
      not only did the Vikings fall to 11-4, they also surrendered homefield advantage
      to the Saints.

  - context: Hoping to rebound from their loss to the Patriots, the Raiders stayed at
      home for a Week 16 duel with the Houston Texans.  Oakland would get the early
      lead in the first quarter as quarterback JaMarcus Russell completed a 20-yard
      touchdown pass to rookie wide receiver Chaz Schilens.  The Texans would respond
      with fullback Vonta Leach getting a 1-yard touchdown run, yet the Raiders would
      answer with kicker Sebastian Janikowski getting a 33-yard and a 30-yard field
      goal.  Houston would tie the game in the second quarter with kicker Kris Brown
      getting a 53-yard and a 24-yard field goal. Oakland would take the lead in the
      third quarter with wide receiver Johnnie Lee Higgins catching a 29-yard touchdown
      pass from Russell, followed
