Nested arrays of grazing incidence mirrors allow astronomers to focus radiation.

Nested  array  of  grazing  incidence  mirrors  allow  astronomers   to  focus  X-ray  radiation.  The astronomer  x-ray  deal  with  the  study  of  x-ray observation  and   detection  from  astronomical  object.The x-ray   detectors and  Telescopes   are  taken  to  high altitude or  into  space  by  balloons.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

Ibelieve the correct answer would be c.
