Believe it or not, no one can afford to deny or ignore the tiny sparkle of an idea, especially in a/an 【C1】______ of knowledge explosion.

During the year of 1994, they 【C7】______ Yahoo into a customized database designed to 【C8】______ the needs of the thousands of users that began to use the service through the closely 【C9】______ Internet community. They developed customized software to help them 【C10】______ locate, identify and edit material 【C11】______ on the Internet.

In early 1995 Marc Andersen, one of the 【C16】______ of Netscape Communication in Mountain View, California, invited Filo and Yang to move their files 【C17】______ to larger computers 【C18】______ at Netscape. As a result Stanford"s computer network returned to 【C19】______ and both parties benefited from this issue. Today, Yahoo 【C20】______ organized information on tens of thousands of computers linked to the web.
