"As Earth was being formed out of the collision of space rocks, the heat from those

collisions and from the increasing gravitational energy of the planet made the entire

planet molten, even the surface. Any water present would have evaporated and gone off

into space. As the planet approached its current size, however, its gravitation became

strong enough to hold gases and water vapor around it as an atmosphere. Because

comets are largely ice made up of frozen water and gases, a comet striking Earth then

would have vaporized. The resulting water vapor would have been retained in the

atmosphere, eventually falling as rain on the cooled and solidified surface of Earth.

Therefore, the water in Earth's oceans must have originated from comets."

31) The following appeared in a medical newsletter.

"Doctors have long suspected that secondary infections may keep some patients from

healing quickly after severe muscle strain. This hypothesis has now been proved by

preliminary results of a study of two groups of patients. The first group of patients, all

being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports

medicine, took antibiotics regularly throughout their treatment. Their recuperation time

was, on average, 40 percent quicker than typically expected. Patients in the second

group, all being treated by Dr. Alton, a general physician, were given sugar pills,

although the patients believed they were taking antibiotics. Their average recuperation

time was not significantly reduced. Therefore, all patients who are diagnosed with

muscle strain would be well advised to take antibiotics as part of their treatment."

a large architectural firm.

"Several well-known, retired architects were interviewed in Architecture Today about

changes in the field. Only one had earned a college degree in architecture. All others had

come into the field at an early age by serving apprenticeships that required them to work

under the direct supervision of an experienced architect. Several of the colleges that we
