Problem: "story": "Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals.

The beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 10,200 8,800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called "proto-Neolithic" is now included in the Pre-Pottery Neolithic (PPNA) between 10,200 and 8,800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming."
Solution: What did Neolithic follow?
Explanation: This question is based on the following sentence in the passage - the Neolithic followed the terminal Holocene Epipaleolithic period and this is answerable from the passage. So, it is a good question.

Problem: CHAPTER VIII

A MYSTERIOUS LETTER

In the morning mail Gus Plum received a letter postmarked London which he read with much interest. Then he called on Dave.

"I've just received a letter I want you to read," he said. "It is from Nick Jasniff, and he mentions you." And he handed over the communication.

It was a long rambling epistle, upbraiding Plum roundly for "having gone back on him," as Jasniff put it. The writer said he was now "doing Europe" and having a good time generally. One portion of the letter read as follows:

"The authorities needn't look for me, for they will never find me. I struck a soft thing over here and am about seventy pounds to the good. Tell Dave Porter I could tell him something he would like to hear--about his folks--but I am not going to do it. I don't think he'll meet that father of his just yet, or that pretty sister of his either. She'd be all right if she didn't have such a lunkhead of a brother. Tell him that some day I'll square up with him and put him in a bigger hole than he got me into. If it wasn't for him I wouldn't have to stay away as I'm doing--not but what I'm having a good time--better than grinding away at Oak Hall."

As may be imagined, Dave read this letter with even greater interest than had Gus Plum. What was said about his father and sister mystified him.
Solution:
Who sent the letter?
