Hello. You did not inform what work this question refers to, but through the context of the question and the name of the character, we can consider that you are referring to the theater play "Anne Frank" that reproduces Anne Frank's account of the time that she went into hiding with her family before being deported to a Nazi concentration camp.
Although Anne and her entire family had been in hiding for three years, they had Austrian friends who helped them have supplies necessary for food and hygiene. One of those friends was Mr. Kraler. However, one day he brought a news that caused concern to all the residents of the hideout, which was called a secret annex that was in a commercial building. Mr. Kraler claimed that a warehouse worker could have discovered the Frank family's hiding place and was blackmailing Mr. Kraler so that he would not divulge what he knew. This worried the Franks a lot and is connected to Act 1, as it shows that all the care and preparation of the family to not be discovered, in Act 1, may have been in vain.
People seem to think that the pyramid workers were slaves, which is ridiculous and untrue.
The tone of the original passage is formal. It could be in a trusted, reliable source on Egyptians. The answer has an informal tone. It uses the words "ridiculous" and "untrue". These opinion words make the sentence of opinion not a statement of fact. The original sentence is a statement of fact.
The correct answer is A.) Direct Object.
My reason being is because a direct object is a group of words representing the person or thing upon which the action of a verb is preformed or toward which it is directed.
I hope that this is really helping you a lot.
