QUES: Leibniz describes a space that exists only as a relation between objects, and which has no existence apart from the existence of those objects. Motion exists only as a relation between those objects. Newtonian space provided the absolute frame of reference within which objects can have motion. In Newton's system, the frame of reference exists independently of the objects contained within it. These objects can be described as moving in relation to space itself. For many centuries, the evidence of a concave water surface held authority.

For how long did the evidence of a concave water surface hold authority in reference to space?
What is the answer?
ANS: many centuries
QUES: Compression is useful because it helps reduce resource usage, such as data storage space or transmission capacity. Because compressed data must be decompressed to use, this extra processing imposes computational or other costs through decompression; this situation is far from being a free lunch. Data compression is subject to a spacetime complexity trade-off. For instance, a compression scheme for video may require expensive hardware for the video to be decompressed fast enough to be viewed as it is being decompressed, and the option to decompress the video in full before watching it may be inconvenient or require additional storage. The design of data compression schemes involves trade-offs among various factors, including the degree of compression, the amount of distortion introduced (when using lossy data compression), and the computational resources required to compress and decompress the data.

What must compressed data be to be inconvenient?
What is the answer?
ANS: unanswerable
QUES: In 2000[update], there were 94,367 workers who commuted into the municipality and 16,424 workers who commuted away. The municipality is a net importer of workers, with about 5.7 workers entering the municipality for every one leaving. Of the working population, 50.6% used public transport to get to work, and 20.6% used a private car.

How many workers commute into the municipality?
What is the answer?
ANS:
94,367
