半保存的複製では、DNAの一方の鎖だけが鋳型になりますが、この図では2本とも鋳型になっている(?)のはなぜですか?🙏 お願い致します🙇🏻‍♀️

線を引いたところの訳し方を丁寧に教えて頂きたいです🙇‍♀️

L American poet Ralph Waldo Emerson once said, "Every artist was first an amateur." He likely never thought those words would apply to machines. Yet artificial intelligence (AI) has demonstrated a growing talent for creativity, whether writing a heavy-metal rock album or producing an original portrait that is strikingly similar to a Rembrandt. Applying AI to the art world might seem unoriginal; there are, of course, plenty of humans delivering awe-inspiring work. Supporters say, however, the real beauty of training AI to be creative does not lie in the end product-but rather in the technology's potential to expand on its own machine-learning education, and to solve problems by thinking in different ways far faster and better than humans can. For example, creative problem-solving AI could someday make snap decisions that save the lives of the passengers in a self-driving car if its sensors fail. AI with a creative component will be essential in developing highly automated systems that can respond appropriately to human life, says Mark Riedl, an associate professor at Georgia Institute of Technology's School of Interactive Computing. "The fact is, we do lots of little bits of creativity every single day; lots of problem-solving goes on," Riedl says. "If my son gets a toy stuck under the couch, I have to devise a tool from a hanger to get it out." Riedl points out human creativity is also important in human social interactions, even telling a well-timed joke or recognizing a pun. Computers struggle with such subtleties. An incomplete understanding of how humans construct metaphors, for example, was all it took for an experiment in Al-generated literature to compose a new Harry Potter chapter filled with nonsensical sentences such as, "The floor of the castle seemed like a large pile

①English has become the leading international language because of three rather different developments. Firstly, the language acquired a strong position in large parts of the world as as Britain built and maintained its empire from the seventeenth through to the ( A ) twentieth centuries. Secondly, the United States obtained a leading position in technology, economy, and politics in the first part of the twentieth century, and still retains this status. Thirdly, industry, communications, and international relations developed in such a way in the twentieth century that a common language was much more in demand than before. English was there to fill (a) the need, while the other European languages had been pushed aside for different reasons. As the *prominent position of English arises from the three factors mentioned, attitudes towards the language among people outside the English-speaking countries may vary accordingly.

All these views are justified to some extent. Different opinions tend to prevail in different parts of the world.
