A sequential algorithm is broken into three stages Sequential Algorithm Time

Download stage: 1 minute
Sorting stage: 6 minutes
Upload stage: 1 minute
A parallel version of the algorithm completes the sorting stage in parallel leading to a new set of times

What is the speedup of the parallel solution?

A. 6 minutes
B. 4 minutes
C. 2
D. 3

2

Explanation:

1+6+1=8

1+2+1=4

8/4=2

The qustion is asking for the parallel solution speadup.  It is a common mistake to give the speedup for for just the sorting stage 6/2=3.

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?

yes, but you must first make sure that you'll be able to make your turn or you can crash into other vehicles.
