Question

originally, the world wide web contained no pictures or cartoons or sounds. web pages contained only words. but in 1993, the first graphical web browser was released - that is, a web browser that can include pictures. it was called mosaic and it was given away free by programmers at the national center for supercomputing applications (ncsa) at the university of chicago. many of the most popular web browsers around today are based on mosaic. mosaic was ____

comical

cavalier

magnetic

unprecedented

Explanation:

The text states that in 1993, the first graphical Web browser (Mosaic) was released. Before that, the World Wide Web had no pictures. So Mosaic was the first of its kind (graphical browser), which means it was unprecedented (never done or known before).

• "comical" means funny, which has no relation to the context.
• "cavalier" means showing a lack of proper concern, not relevant here.
• "magnetic" relates to magnetism, not relevant to the description of Mosaic.

Answer:

unprecedented
