Article: President Obama: I want to welcome Vice President Xi to the Oval Office and welcome him to the United States. This is obviously a great opportunity for us to build on the U. S.-China relationship, but also an opportunity to return the extraordinary hospitality that Vice President Xi showed Vice President Biden during his recent visit to China. As I indicated during my recent visit to APEC and the East Asia Summit, the United States is a Pacific nation. And we are very interested and very focused on continuing to strengthen our relationships, to enhance our trade and our commerce, and make sure that we are a strong and effective partner with the Asia Pacific region. And obviously, in order to do that, it is absolutely vital that we have a strong relationship with China. So, Mr. Vice President, I hope you have a wonderful visit while you're here. I'm sure the American people welcome you. I'm glad that you're going to get an opportunity to get out of Washington. I know you'll be visiting Lowa, which you visited many years ago when you were governor. And I understand you're also going to Los Angeles and maybe even taking in a Lakers basketball game. So I hope you enjoy that very much. I want to extend my deepest welcome to you, and look forward to a future of improved dialogue and increased cooperation in the years to come.

Article: Botany , the study of plants, occupies a particular position in the history of human knowledge.For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest ) of insights.It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient.This is logical.Plants are the basis of the food pyramid for all living things even for other plants.They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes.Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each.To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all. Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows.Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple.When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season--the first, great step in a new association of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture: cultivated crops.From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away. Question: We learn that the first great step toward the practice of agriculture is _ . Yes or no, is the answer "the discovery of certain grasses that could be harvested and replanted"?
(Answer)
No
