The correct answer should be additionally.
The word additionally would provide the best transition between these two sentence. It is so because you have one idea in the first sentence, and then you want to show another idea very similar to the first one in the second sentence. Using additionally to convey that is the way to go.
The sentence which uses quotation marks correctly is: "How are your classes?" asked Xavier. When using quotation marks with a question sentence, always include the question mark inside the quotation marks and a comma after the quoted sentence is no longer necessary.
<u>O way it handles things on streets</u>
Explanation:
There is a needless ambiguity in this phrase that would just confuse the reader. it is not good prose when you can use just as many words and explain what the problem is but instead just use the word 'things' to describe them.
<u>The sentence begs to understand what exactly it is that the car does not understand on the road or has a difficulty to follow but this is left unanswered in the text of the paragraph.</u>
So this is where the author must re question their word choice for the passage.
