### HideShow timer Statistics

The West Indian manatee, a distant relative of the elephant, returned to the sea some 50 million years ago. These thousand-pound herbivores inhabit the warm coastal waters where Americans like to play. Despite conservation efforts, criminal penalties for harming these creatures, and an overabundance of SAVE THE MANATEE! bumper stickers, none of these animals can be considered safe.

Which of the following, if true, most strongly supports the argument above?

a) Last year, several manatees were mysteriously killed by an unidentified toxin.

b) All manatees swim at depths that make them vulnerable to the blades of motorboat engines.

c) Most tourists are unaware of the ongoing efforts to save the manatee.

d) The population of manatees in the wild has dwindled to fewer than 2,500 animals.

E) Although dozens of manatee deaths are documented each year, many more deaths go unreported.

Which of the following, if true, most strongly supports the argument above?

a) Last year, several manatees were mysteriously killed by an unidentified toxin.
(this talks only about last year)

b) All manatees swim at depths that make them vulnerable to the blades of motorboat engines.
(possible, passage doesn't state anything being done for motorboats)

c) Most tourists are unaware of the ongoing efforts to save the manatee.
(if thers "an overabundance of SAVE THE MANATEE! bumper stickers" then this doesn't seem right)

d) The population of manatees in the wild has dwindled to fewer than 2,500 animals.
(we don't know what was the original population)

E) Although dozens of manatee deaths are documented each year, many more deaths go unreported.
(though this is relevant , it does not help to fill in the gap between "efforts being done" & "still considered unsafe" )

B for me

My line of thought -

Conclusion - Despite conservation efforts, criminal penalties for harming these creatures, and an overabundance of SAVE THE MANATEE! bumper stickers, none of these animals can be considered safe

Premise - These thousand-pound herbivores inhabit the warm coastal waters where Americans like to play.

Lets look at the options.

a) Last year, several manatees were mysteriously killed by an unidentified toxin.
Does not support the premise or conclusion.
b) All manatees swim at depths that make them vulnerable to the blades of motorboat engines.
Supports the premise.
c) Most tourists are unaware of the ongoing efforts to save the manatee.
Does not support the conclusion.As the argument mentions that there are lot bumper stickers.
d) The population of manatees in the wild has dwindled to fewer than 2,500 animals.
Out of context.
E) Although dozens of manatee deaths are documented each year, many more deaths go unreported.
Does not support the conclusion.
