What conditions are necessary for a total lunar eclipse? a) new moon phase, three bodies in alignment, Earth between Sun and Moon
b) full moon phase, three bodies in alignment, Earth between Sun and Moon
c) new moon phase, three bodies in alignment, Moon between Sun and Earth
d) full moon phase, three bodies in alignment, Moon between Sun and Earth

Explanation:

For a lunar eclipse to occur, the Sun, Earth, and Moon must be roughly aligned in a line. Otherwise, the Earth cannot cast a shadow on the Moon's surface and an eclipse cannot take place. When the Sun, Earth, and Moon come together in a straight line, a total lunar eclipse takes place.

explanationyou have to add as well to be it could be

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
