[Q]: Paragraph- Sent 1: During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors.
Sent 2: The Greeks regarded the gesture as the province of deities and believed that Alexander meant to deify himself by requiring it.
Sent 3: This cost him the sympathies of many of his countrymen, and he eventually abandoned it.
Sent 4: A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander.
Sent 5: The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance.
Sent 6: Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgemental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle.
Sent 7: Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages.
Sent 8: His official historian, Callisthenes of Olynthus, was implicated in the plot; however, historians have yet to reach a consensus regarding this involvement.
Sent 9: Callisthenes had fallen out of favor by leading the opposition to the attempt to introduce proskynesis.
Question: Why did Parmenion have to die?.
[A]: The death of the son necessitated the death of the father.

[Q]: Paragraph- Sent 1: You may be wondering, how can a glacier get so big?
Sent 2: Why does it move?
Sent 3: These are both good questions.
Sent 4: In the winter months, precipitation falls as snow.
Sent 5: This solid form of water builds up on the ground as long as the temperatures stay cold enough.
Sent 6: As the temperature rises, the snow starts to melt.
Sent 7: The frozen water changes state back into a liquid state.
Sent 8: Nearer the poles, summer does not last very long.
Sent 9: If the summer is long enough and warm enough, all the snow may melt.
Sent 10: This is what typically happens now.
Sent 11: The earth was a little cooler 12,000 years ago.
Sent 12: As a result, during the summer months, that amount of snow did not melt.
Sent 13: It may have only been an inch or so of snow that melted.
Sent 14: The following winter, snow fell on top of this left-over snow.
Sent 15: This next winters snowfall had a head start.
Sent 16: Year after year, the snow that did not melt became thicker and thicker.
Sent 17: Inch by inch the snow started to build up.
Sent 18: Over many years, layer upon layer of snow compacted and turned to ice.
Question: Are temps always the same in glacier areas?.
[A]: No.

[Q]: Paragraph- Sent 1: (CNN) -- The U.S. space shuttle program retired in 2011, leaving American astronauts to hitchhike into orbit.
Sent 2: But after three long years, NASA's successor is almost ready to make an entrance.
Sent 3: Orion, the agency's newest manned spaceship, is being prepared for its first mission in December.
Sent 4: In future missions, it will journey into deep space -- to Mars and beyond -- farther than humans have ever gone before.
Sent 5: Orion comes loaded with superlatives.
Sent 6: It boasts the largest heat shield ever built and a computer 400 times faster than the ones on the space shuttles.
Sent 7: It will be launched into space on the most powerful rocket NASA has ever made.
Sent 8: No astronauts will be aboard the December flight, which will test the spacecraft's systems for future manned missions.
Sent 9: Final work on the spacecraft is under way at the Kennedy Space Center in Florida.
Sent 10: Orion came one step closer to completion this month with the stacking of the crew module atop the service module.
Sent 11: "Now that we're getting so close to launch, the spacecraft completion work is visible every day," Orion Program Manager Mark Geyer said in a statement.
Sent 12: A 3,600-mile journey When complete, the Orion capsule will resemble a fencing foil, with a tall spire shooting up from a rounded base.
Sent 13: At the top will sit a launch abort system, with downward-facing thrusters that would save the crew from a jarring crash in the event of a rocket malfunction.
Sent 14: The bottom portion, the service module, will perform various functions such as in-space propulsion and cargo storage.
Sent 15: Nestled between the two will be the crew module, capable of supporting human life from launch until recovery.
Sent 16: Attached to the service module will be a United Launch Alliance Delta IV Heavy rocket.
Sent 17: For the first time since the space shuttle's debut launch in 1981, the crew compartment will ride on the tip of the rocket rather than hanging onto its side, evoking the configuration of the famous Apollo or Gemini missions.
Question: What will the Orion allow NASA to do and why?.
[A]:
Orion comes loaded with superlatives.
