Why can "The tiger is endangered" refer to ALL tigers, while "The tigers in this zoo are endangered" cannot?
"The" + a singular animal name refers to the whole species (formal). In the second sentence, "in this zoo" narrows it to one specific group.
This sounds natural, so what is wrong with it? "Of the two proposals, the cheaper one is definitely the best."
"The best" is a superlative, which needs three or more things. With exactly two, it must be "the better."
In "The harder you work, the more you achieve," is "harder" an adjective or an adverb? Define both terms and explain how you can tell.

Correct: "The volunteers collected several informations about nesting sites, but none of them were reliable."
The volunteers collected some information about nesting sites, but none of it was reliable.
"Information" is uncountable, so "informations," "several," "them" and "were" all have to change.
