Answer: Hailstones, even the smallest kind can inflict damage to crops. The results will lead to deformations due to tissue damage. Later on after being grown the plant can be completely ruined due to the damage it took. If not yet strong enough to withstand the physical damage it can break them and they will die very early in development
Hope this helps ^^
Affected would be your answer...affected means something attacked the body...effected means it did not attack the body...just showed symptons
Exposition is the answer because they are wrapping the whole story up saying there is no knight like Lochinvar
