I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are generally considered as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from electronic toys to industrial robots are the most numerous."?
The answer to this question is:
A smartphone may also be referred to as what type of device?
