Article: I recently had dinner with someone who told me that one of his best friends had been killed in a private plane crash, and something happened at the memorial service that he'll never forget. He shared the story with me. At the memorial service, his friend's wife walked to the platform to speak to the gathering. She said a friend had asked her the best memory she had of their life together. At the moment, she had been too sad to answer, but she had thought about it since and wanted to answer the question. They were in their late forties when he died, and she began talking about a time in their life almost twenty years earlier. She had quit her job to obtain her master's degree, and her husband never hesitated in his support. He held down his own job and also did the cooking, cleaning, and other housework while she studied for her degree. One time they both stayed up all night. She was finishing her paper, and he was preparing for an important business meeting. That morning, she walked out of her study, leaned against the door by the stairs, looked at her husband downstairs and just thought about how much she loved him. She knew how important this meeting was to his future, and she was feeling guilty that she didn't even have time to make his breakfast. He took his briefcase and hurried out. She heard the garage door open and close, but much to her surprise, she heard it open again about thirty seconds later. From above, she watched her husband dash into the house and walk over to the forgotten coffee table. Marking the surface of it with his finger through the dust with the words "I love you", then he raced back to his car. The new widow then looked out at her audience and said, "John and I had a wonderful life together. We have been around the world several times. We've had everything money can buy...but nothing comes close to that moment." Hearing this, I was deeply moved. "Love makes life worthwhile." Question: The woman mentioned an incident 20 years ago to show _ . Yes or no, is the answer "how her husband loved her"?
No

Article: Legend has it that sometime toward the end of the Civil War (1861 - 1865) a government train carrying oxen was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived? The answer lay in a resource that unknowing Americans had trampled underfoot in their haste to cross the "Great American Desert" to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the west, that familiar blue joint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, not only were they immune to drought, but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year, for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses. Question: Which of the following was NOT mentioned as a characteristic of western grasses? Yes or no, is the answer "They can be grown indoors."?
No
