Which letter is used incorrectly?
a. dressage is a form of equestrian competition that requires subtle guidance of a horse through complex maneuvers.
b. equestrian troops are inefficient in modern warfare.
c. a race horse can be trained to be an obedient equestrian.
d. in the louvre in paris you can see a ninth-century equestrian statue of the french emperor charlemagne as well as the portrait of mona lisa.
the word is equestrian.

I believe the answer is C.

Explanation:

A race horse cannot become an equestrian because an equestrian is the rider of the horse. The racehorse could become an obedient mount for an equestrian, but it cannot be an equestrian itself unless it magically turns into a human!

hope this helps :)

the author is intending to draw attention to the plight of refugees, editorial and biography support this. both workpieces make the reader empathize with enrique as well as with the other young migrants from central america. the writer, however, is using a different approach to each text.

the editorial includes strong words to persuade readers. he is trying hard to convince readers in the us to change its refugee approach.

the biography relies on narrative techniques and figurative language which the writer uses wisely in the setting, characterization, and personification to educate readers on the topic.

i think it may be b, i'm not exactly too sure on this. but b seems to make more sense.
