The statements, along with the literary device used in each, are below:
“The Army Alpha is cleverly designed"
-- This is an example of understatement. By describing the Army Alpha as cleverly designed, the speaker is downplaying the scope of the test. We are told the told the test will show the Army everything about you. Therefore, it is an understatement to say it is "cleverly designed."
“I guess that the letter was the last straw”
-- This is an example of an idiom. An idiom is a figure of speech whose meaning seems unrelated to the words used. The phrase "the last straw" has nothing to do with straws: it is a figure of speech used to explain when someone has run out of patience, etc. Therefore this is an example of an idiom.
“I took the opportunity to vomit out a Niagara of vitriol”
-- This is an example of hyperbole. Hyperbole is extreme exaggeration. Since it is impossible to vomit a literal waterfall of anything, this statement is hyperbole.
“Army Intelligence called me up in about a week, wanting to chat”
-- This is an example of irony. Army Intelligence is not calling for a chat. The speaker is being sarcastic, or ironic. Army Intelligence is going to interrogate the speaker in the presence of his lawyer. A "chat" this is not.
The part of the letter that needs revision in order to be an appropriate formal letter is the salutation. A letter should always include a salutation other than just writing the name of the person. The salutation should be brief, but it helps to introduce the message that needs to be delivered without setting a rude or sharp tone.
The sentence that uses correct spelling is the first sentence.
The correct answer is A. 1809-1849.
B makes sense, because when you are translating from another language there are often many different words that mean the same thing. Therefore, the translator would get to choose which one to use.
This is not really a structural decision, but it is the only answer which would stay true to the original story. The translator’s job is the change the language. not the whole story. Therefore, A, C, or D can not be correct.
