[Q]: Passage: Since the 2005 revival, the Doctor generally travels with a primary female companion, who occupies a larger narrative role. Steven Moffat described the companion as the main character of the show, as the story begins anew with each companion and she undergoes more change than the Doctor. The primary companions of the Ninth and Tenth Doctors were Rose Tyler (Billie Piper), Martha Jones (Freema Agyeman), and Donna Noble (Catherine Tate) with Mickey Smith (Noel Clarke) and Jack Harkness (John Barrowman) recurring as secondary companion figures. The Eleventh Doctor became the first to travel with a married couple, Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill), whilst out-of-sync meetings with River Song (Alex Kingston) and Clara Oswald (Jenna Coleman) provided ongoing story arcs. The tenth series will introduce Pearl Mackie as Bill, the Doctor's newest traveling companion. Question: Who were the secondary companions of the Ninth and Tenth Doctors?
[A]: Mickey Smith (Noel Clarke) and Jack Harkness (John Barrowman)

It is a single-step, 5-cylinder engine (no compound) with superheated steam and consumes approx. 4 kg (8.8 lb) of steam per kWh.[not in citation given] Question: How many pounds of steam per kilowatt hour does the Energiprojekt AB engine use?

[Q]: Passage: With 4:51 left in regulation, Carolina got the ball on their own 24-yard line with a chance to mount a game-winning drive, and soon faced 3rd-and-9. On the next play, Miller stripped the ball away from Newton, and after several players dove for it, it took a long bounce backwards and was recovered by Ward, who returned it five yards to the Panthers 4-yard line. Although several players dove into the pile to attempt to recover it, Newton did not and his lack of aggression later earned him heavy criticism. Meanwhile, Denver's offense was kept out of the end zone for three plays, but a holding penalty on cornerback Josh Norman gave the Broncos a new set of downs. Then Anderson scored on a 2-yard touchdown run and Manning completed a pass to Bennie Fowler for a 2-point conversion, giving Denver a 24–10 lead with 3:08 left and essentially putting the game away. Carolina had two more drives, but failed to get a first down on each one. Question: What was the time on the clock when Carolina got the ball to their 24-yard line in the fourth quarter?
[A]:
4:51
