OA "the Ministry said, 'and various scientists who have researched
dolphin behavior have suggested that (they have) unusually high
intelligence... compared to other animals." ( Paragraph 3)
OB "Big-brained animals almost certainly wouldn't want to spend years
lugging polyester-skinned mammals across shallow swimming
pools six days a week." ( Paragraph 6)
OC "Twenty-four dolphins, after years of service, were being
'reassigned, the story said, so that sea drones, or unmanned
underwater vehicles (UUVs, in Navy parlance) could take their

OD "That, of course, was my mind shouting: what the dolphins were

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.

the correct answer is d. in john paston's letter written friday, 14, 1476, he expresses his fear that he may have to go to war.

indeed, although the black death was ravaging europe, the pastons were relatively safe from it due to their social status as they were part of the landed gentry. it is clear that the vast majority of the victims of the pandemic were the poor. the reason why he is weary of having to go to war is because at the particular time england was also devastated by the war of the roses and paston, being a courtesan was inevitably involved.
