The answer is D. As her leg jiggled up and down, she chewed a ragged nail and checked her watch.
Explanation:
Syntax is a component of language that focuses on the arrangement of elements or structures used to convey ideas. Traditional syntax follows the subject-predicate structure; this means the agent of the action is followed by the action. This arrangement can be seen in the section "she (subject) chewed (verb) a ragged nail and checked (verb) her watch".
Besides this, to preserve the traditional structure other details such as complementary clauses are usually placed at the beginning and separated by a comma or similar punctuation. This occurs in "As her leg jiggled up and down" because this detail complements the sentence and is placed before the main clause separated by a comma.
In the story 'The River' by Mark Twain, he uses an extended metaphor, comparing the Mississippi river to books, art, and poetry. In ‘reading the river’ the pilot’s rigorous study of the river is referred to, Twain regard this as reading a book.
“The face of the water in time became a wonderful book- a book that was a dead language to the uneducated passenger but which told its mind to me without reserve, delivering its most cherished secrets as clearly as if it uttered them with a voice.”
In the above line, Twain compares water to the book. The sight of the pilot is compared to that of passenger’s is another extended metaphor used. He compares it with “italicized passages”, “shouting exclamation points” and the “pretty pictures". To the pilot’s eye, such features of the river becomes the language of water. However, how the river is being read as a book depends upon one’s experience who is reading, as it can have different meanings.
Italian dressing is a heterogeneous mixture because the mixture contain substances of different phase. There are both liquid and solid in the dressing, therefore it is heterogeneous. If it is homogeneous, the dressing will be all liquid (or all solid but I don't think it will taste good anymore). Idk if this is the answer you want.
