Read this excerpt from a speech in support of the popular election of the president of the united states:

i’m standing before you to make the case for the election of our president by popular vote. the current system wherein the electoral college casts the deciding vote for who becomes our next president is an anachronism that has outlived its usefulness. you only have to look at what happened in the election of 2000 when the candidate who got the most popular votes was denied the office because he lost the electoral vote. i say now is the time to end this travesty!

which change is the best revision to reflect a formal tone for the speech’s audience?

a. change “wherein” to “whereby.”
b. change “you only have to look at” to “one only has to remember.”
c. change “anachronism” to “a throwback to the past.”
d. change “i say now is the time” to “i believe now’s the time.”
