Which of the following networks had these two goals: a) allowing scientists to work together on scientific projects; and, b) functioning even if part of the network was destroyed by a nuclear attack?

ARPANET

Explanation: ARPANET is network based on the internet which uses the technique of sending data in small packets/units known as packet switching . It helps in effective communication in the field of military while even some nuclear attack destructs the network. It was a method used in the scientific field for the ease of work of scientists by linking different computers to work with high processing and power.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
