The symptoms that US president Zachary Taylor began showing five days before his death are consistent with arsenic poisoning. Recent examinations of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries. These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal does of the poison.
The president showed symptoms that were similar to those of Arsenic poisoning for five days before his death. This increases the probability of Mr Taylor dying as a result of the arsenic poisoning.
However, the examinations of the bones show two results that go against the above probability. One, the levels of arsenic remain the same as those in bones of his contemporaries, and second, the levels are lower than would be in a person who has stayed alive for more than one day after poisoning. It doesn’t matter if we do not know how the quantity of arsenic actually varies with days after ingesting a lethal dose. But, we can surely say from argument that more the days, more should be the level. The other inference is that Mr Taylor was not alive for more than a day after ingesting a lethal dose of poisoning, if at all he died due to arsenic poisoning.
Which of the following is most strongly supported by the statements given?
Quote:
(A) The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning
Nowhere the symptoms shown have been questioned. They are consistent with arsenic poisoning and we cannot comment on consistency with other types of poisoning.
Quote:
(B) Taylor's death was not the result of arsenic poisoning
Could be a very tempting answer. But what we can infer for sure is that he did not live for more than a day after the lethal dose if his death was result of arsenic poisoning.
The possibility of his dying within a day of ingesting of lethal dose of arsenic poisoning remains and is same as possibility of his dying due to heart failure or due to intake of any other substance. .
Quote:
(C) The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic
The symptoms were similar to those of arsenic poisoning, but were not caused by a lethal dose of arsenic poisoning.
He would not have remained alive with these symptoms for five days. If the symptoms were indeed those of arsenic poisoning, the levels of arsenic in bones would have been more than were actually found. Correct.
Quote:
(D) The symptoms that Taylor began showing five days before his death grew more severe each day
The para does not give any information on severity of symptoms.
Quote:
(E) It is unusual for a person who has ingested a lethal dose of arsenic to live for more than a day
The para nowhere suggests that.
C is the correct answer.
