Which is considered by many to be the first work of pop art

Iwas told to ask others what they think life is.

Stanley, an art historian specializing in european history, wrote a critique of this painting for a newspaper. in a part of the critique, he wrote, “the overall effect of the work suggests that the artist understands the romance of venice and its boating culture.” which step of the critique does this statement represent?

Which of these is a consistent periodic pulse separated into equivalent intervals of time?
