[EX Q]: story: I'm writing this letter slowly because I know you can't read fast. We don't live where we did when you left home. Your dad read in the newspaper that most accidents happened within 20 miles from our home, so we moved.

I won't be able to send you the address because the last family that lived here took the house numbers when they moved so that they wouldn't have to change their address. This place is really nice. It even has a washing machine. I'm not sure it works so well though: last week I put a load in and pulled the chain and haven't seen them since. The weather isn't bad here. It only rained twice last week; the first time for three days and the second time for four days. About that coat you wanted me to send you, your uncle Stanley said it would be too heavy to send in the mail with the buttons on so we cut them off and put them in the pockets.

John locked his keys in the car yesterday. We were really worried because it took him two hours to get me and your father out. Your sister had a baby this morning, but I haven't found out what _ is yet. The baby looks just like your brother.

Uncle Ted fell in a whiskey vat last week. Some men tried to pull him out, but he fought them off playfully and drowned. We had him cremated and he burned for three days.

Three of your friends went off a bridge in a pick-up trunk. Ralph was driving. He rolled down the window and swam to safety. You other two friends were in back. They drowned because they couldn't get the tail gate down.

There isn't much more news at this time. Nothing much has happened.

Love,

Mom

P.S. I was going to send you some money but the envelope was already sealed., question: Why didn't she?
[EX A]: the envelope was sealed

[EX Q]: story: CHAPTER IV.

Signor Andrea D'Arbino, searching vainly through the various rooms in the palace for Count Fabio d'Ascoli, and trying as a last resource, the corridor leading to the ballroom and grand staircase, discovered his friend lying on the floor in a swoon, without any living creature near him. Determining to avoid alarming the guests, if possible, D'Arbino first sought help in the antechamber. He found there the marquis's valet, assisting the Cavaliere Finello (who was just taking his departure) to put on his cloak.

While Finello and his friend carried Fabio to an open window in the antechamber, the valet procured some iced water. This simple remedy, and the change of atmosphere, proved enough to restore the fainting man to his senses, but hardly--as it seemed to his friends--to his former self. They noticed a change to blankness and stillness in his face, and when he spoke, an indescribable alteration in the tone of his voice.

"I found you in a room in the corridor," said D'Arbino. "What made you faint? Don't you remember? Was it the heat?"

Fabio waited for a moment, painfully collecting his ideas. He looked at the valet, and Finello signed to the man to withdraw.

"Was it the heat?" repeated D'Arbino.

"No," answered Fabio, in strangely hushed, steady tones. "I have seen the face that was behind the yellow mask."

"Well?"

"It was the face of my dead wife."

"Your dead wife!"

"When the mask was removed I saw her face. Not as I remember it in the pride of her youth and beauty--not even as I remember her on her sick-bed--but as I remember her in her coffin." , question: Did he find anyone there?
[EX A]: the marquis's valet

[EX Q]: 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., question: What was the Neolithic considered?
[EX A]:
the last part of the Stone Age
