DESPERATE. I WILL GIVE BRAINLIST AND THANKS Many people think that biofuels are the solution to a lot of the problems of climate change, but others disagree. What requirements would biofuels have to meet if they were to be really effective at replacing gasoline in motor vehicles?

hi there!

moors is essentially another word for muslims.

the moors invaded spain around year 700, during their time ruling spain the muslims promoted religious tolerance (moors tolerated jews who were viewed as outcasts by northerners), the moors as well had a great impact on their language, and architecture (palaces were created).

i hope this !

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
