The contrast drawn between the Haicheng earthquake in Paragraphs 2 and 3 and the Tangshan earthquake in Paragraph 3 contributes to a central idea that earthquakes are
А
all preceded by reliable signs, and therefore scientists have the ability to predict
earthquakes.
B
controlled by observable factors that just average citizens can report to the
authorities.
с
not always predictable, so new methods and more studies need to be
conducted
D
not often studied because there is no possible solution to the problem of
predicting earthquakes.

the correct answer would be d, i never like waking up.

explanation:

iambic tetrameter is a meter which is basically a line consisting of four feet of iambic and it is used in poetry. it consists of unstressed syllables followed by a stressed syllable. in this question, the only statement which is giving the feel of being stressed is option d, which says that i never like waking up. it means the person is feeling stressed whenever he wakes up. he never likes to wake up and and whenever he wakes up, he doesn't like it. so a sense or feel of being stressed is in this statement.
