Challenging
A historian is analyzing two documents about the *preconditions* for a revolution. Document A lists economic inequality, while Document B lists political oppression. To synthesize these sources for an argumentative essay, what must the historian do?
A.Choose only the document that seems more important and ignore the other.
B.Argue that neither source is correct because they disagree.
C.Explain how both economic and political factors were necessary conditions that existed *before* the revolution could occur.
D.Focus only on the events that happened after the revolution started.
Challenging
An author writes, 'His *premonition* of disaster was dismissed as mere anxiety.' Why is 'premonition' a more precise and powerful word choice in this context than 'early guess'?
A.'Premonition' implies a supernatural or intuitive feeling of a future event, adding a layer of depth and mystery.
B.'Early guess' is more formal and academic, so it would be a better choice.
C.'Premonition' is easier for the reader to understand.
D.There is no significant difference; the words are interchangeable.
Challenging
A student argues that since 'prejudice' means to 'pre-judge,' it is a neutral term simply meaning 'to make a judgment beforehand.' Using the tutorial's concepts, what is the strongest counter-argument?
A.The prefix 'pre-' is always negative, so the student is wrong from the start.
B.The word's meaning is defined by its Latin root, which is neutral, so the student is correct.
C.While 'pre-' is neutral, the word 'prejudice' has evolved through context to almost exclusively mean an unfair, preconceived opinion not based on reason or experience.
D.The student is correct because the 'Meaning Transformation Rule' only changes the time frame, not the connotation.
