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"?
No

Last night,I went to visit my friends and we spent the next hour talking about that missing feeling we all shared-our families,our friends,our old lives--and soon the sadness turned to fondness.One by one our friends came in to say goodnight and the room was filled with girls,all laughing and sharing our high school experiences.It wasn't until about l:00 a.m.that I turned to my roommate,unconsciously saying,"It's getting late...we should probably go home soon."I was taken aback by my own words.Somehow in the few hours,my dorm room had turned into a home. Question: What made the author begin to take college as a home? Yes or no, is the answer "Friends' shared feelings."?
