all of the following are benefits resulting from the construction of the aswan high dam in egypt except

a.
the floodwaters of the nile are controlled
b.
more arable land is created using irrigation from the dam’s reservoir
c.
the dam generates 15% of egypt’s electricity
d.
the nile river delta ecosystem is protected

The benefits are all except: "The Nile River Delta ecosystem is protected"

Explanation:

The Aswan High Dam in Egypt created many benefits. But it did change the ecosystem. Any plant or animal that depended on the annual flooding could be at risk.

Hope this helps :-)

no questions on whether they are allowed that right

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."
