Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "
The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.
Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.
Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.
Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.

Answer:
parallel and intersect at right angles
Explanation:
The roads in the urban areas tend to be very well organized and constructed. They tend to be parallel to each other, and also to intersect at right angels. The reason for this kind of building of the roads in the urban areas is to make the movement in the urban areas much easier and more efficient, mostly putting the accent on the traffic. It is a fact that the traffic is a big problem in the urban areas, so by constructing the roads in a well organized manner, the traffic jam eases up and the citizens can move more easily and quickly.
