Instrução: A questão está relacionada ao texto abaixo.

Consider the statements below.

I - The use of present perfect simple in the clause No other animal has managed to change its ecological niche so radically (l. 08-09) implies that the author considers the event referred to finished and unrelated to the present.

II - The use of simple past in More recently, humanity discovered (l. 39) is a deviation from the standard norm, and the fragment would be made grammatically correct if its verb tense were the present perfect simple since the event it refers to is said to be recent.

III- The use of passive voice in the clause These parameters are carefully chosen (l. 24-25) means that the author does not know or prefers not to stress who or what makes the choice referred to.

Which ones are correct according to the text?
