In the second paragraph, what is the idea the author is trying to convey about the book, using descriptors like "not textbooks," "impressionistic," and "introductions"? that anyone can misinterpret the meaning of the books that anyone can understand and enjoy the books that the books are less expensive and more useful that the books are less frivolous and more academic

Your question is missing the paragraph of "Preface to Buddhism and Buddhists in China" that will help answer it. I've found it online. The paragraph is as follows:

The purpose of each volume in this series is impressionistic rather than definitely educational. They are not textbooks for the formal study of Buddhism, but introductions to its study. They aim to kindle interest and to direct the activity of the awakened student along sound lines. For further study each volume amply provides through directions and literature in the appendices. It seeks to help the student to discriminate, to think in terms of a devotee of Buddhism when he compares that religion with Christianity. It assumes, however, that Christianity is the broader and deeper revelation of God and the world of today.

The idea the author is trying to convey is:

That anyone can understand and enjoy the books.

Explanation:

In the paragraph of "Preface to Buddhism and Buddhists in China", the author is trying to show his audience that the books they are about to read are not a dense type of literary work. The purpose of the books is not academical in the sense that they do not deepen the studies and explanations about Buddhism. They introduce them in a lighter manner, aiming to get readers interested in the subject rather than transforming them into scholars. They are not textbooks, but a less formally instructional reading that will help readers develop their knowledge and curiosity a little further. Therefore, anyone, scholars or non-scholars, would be able to appreciate and understand the books.

in the short story the slip-over sweater by jesse stuart, the main character and narrator shan is friends with grace, an intelligent girl he has known since childhood and with whom he used to be in love.

at the beginning of the story, shan believes he’s no longer in love with grace, but loves jo-anne instead. in order to buy a slip-over sweater and have jo-anne wear it so that the other students would know she loved him too, shan takes a loan at the bank.

while jo-anne is wearing shan’s sweater, his friend grace starts to wear another popular boy’s one, roy’s sweater. because of that, the other students begin to pay attention to grace and compliment her perseverance and effort. they admire her for walking 5 miles to school every day, despite the weather, and still getting the best grades. shan, who knows all of that for a fact, says, as the narrator, ‘and i knew she had the durability and the toughness of a storm-battered mountain oak.’ he compares his friend’s strength – not only physical, but also of character – to an oak tree, whose wood is known for being sturdy.

as the story goes on, shan changes his behavior out of concern for the debt he has to pay at the bank. his new girlfriend jo-anne never asks him what is wrong nor offers any sort of . instead, she breaks up with shan for not being as fun as she thought he was supposed to be. grace, however, not only asks about shan’s problem, but him make the money he needs. shan can’t but notice how different the girls are and what a wonderful person grace is.   even though he used to find jo-anne prettier at the beginning of the story, he now says, ‘grace was as beautiful as our mountain was in april, prettier than a blossom of wild phlox or a mountain daisy.’ his comparing grace to a mountain or something that exists on a mountain (such as a mountain oak or daisy) certainly has important meaning since shan loves the mountain and everything about it and he knows the mountain thoroughly. shan also loves and knows grace as completely as he does the mountain.
