Choose "extinct" if the species is extinct and "endangered" if the species is endangered.

sixty years ago, as few as 20 whooping cranes were left on earth. now, to conservation efforts, there are more than 300 whooping cranes in the wild.

a. extinct

b. endangered

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

statement #3 on andre"s list is false.
