Why is the law of gravity an example of a universal law?
a- gravity is the attraction of any mass to any other mass.
b- gravity is the force that affects everyone on earth.
c- gravity is the reason the earth revolves around the sun.
d- gravity is the force that exits between any two masses in the universe.

the correct answer is c. the use of consistent patterns that keep the elements in a series in the same form.

  parallel structure, also known as parallelism, is the use of the words in a sentence with the same patterns to attain the same importance for each word. it should be used when connecting words, such as for, and, or etc. are present. one example is: paul likes playing soccer and to swim. (not parallel). paul likes playing soccer and swimming. (parallel)
