a million answer is C 2 answer is D 3 answer is C 4 answer is E 5 answer continues to be E in spite of the incontrovertible fact that it will be "parsecs" or "mega parsecs" 6 all the above. yet im guessing your instructor is questioning telescope. or clock. yet probably telescope. 7 answer is B geometry 8 lunar eclipse is while the earth is right now between the sunlight and moon, leaving the moon in earths shadow. a photo voltaic eclipse is while the moon is between the sunlight and earth and the moon blocks out the sunshine of the sunlight. 9 new moon is while the moon is close to the line of sight of the sunlight. final quarter is while the moon is a million/2 finished yet heading in direction of new section. waning cresent, is the section excellent after new. first quarter is the a million/2 moon heading in direction of an entire moon.
