Hello. Your question is incomplete, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
If the word, to which your question refers, is capable of foreshadowing something, it means that that word is advancing very important information about the plot in a subjunctive way, with the aim of promoting anxiety in the reader, stimulating curiosity, which will keep and will optimize reading.
he correct answer to this open question is the following.
Although you forgot to include the options for this question, we can answer the following.
The word that best describes the author's attitude toward continuing on the "academic road to success" is "Neutral."
It is neutral because the author is just given recommendations on how to approach the road of academic success and life. The author is not being subjective nor adding personal comments that could bias its idea.
For instance, the author is not using optimistic ideas that try to motivate. On the other hand, the author is not adding pessimistic comments that could also bias its information.
That is why "neutral" is the best term to describe the attitude of the author.
The answer is A because an adjective is a word that describes something. When you answer "how many?", your answer is a number. A number is not descriptive.
