The origin of continental nuclei has long been a puzzle. Theories advanced so far have ’generally failed to explain the first step in continent growth, or have been subject to serious objections. It is the purpose of this article to examine the possible role of the impact of large meteorites or asteroids in the production of continental nuclei. Unfortunately, the geological evolution of the Earth’ s surface has had an obliterating effect on the original composition and structure of the continents to such an extent that further terrestrial investigations have small chance of arriving at an unambiguous answer to the question of continental origin. Paradoxically, clues to the origin and early history of the surface features of the Earth may be found on the Moon and planets, rather than on the Earth, because some of these bodies appear to have had a much less active geological history. As a result, relatively primitive surface features are preserved
A. the origin of continents
B. the relationship between astral phenomena and the moon
C. differences of opinion among authoritative geologists
D. the relationship between asteroids and meteorites

Science has long had an uneasy relationship with other aspects of culture. Think of Galileo’ s 17th century trial for his rebelling belief before the Catholic Church or poet William Blake’ s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between sciences and the humanities has, if anything, deepened in this century.
Until recently, the scientific community was so powerful that it could effort to ignore its critics--but no longer. As funding for science has declined, scientists have attacked "antiscience" in several books, notably Higher Superstition, by Paul Regress, a biologist at the University of Virginia, and Norman Leavitt, a mathematician at Rutgers University; and The Demon Haunted World, by Car Satan of Cornell University.
Defenders of science have also voiced their concerns at meetings such as "The Flight from Science and Reason", held in New York City in 1995, and "Sc

Until recently, the scientific community was so powerful that it could afford to ignore its critics- but no longer. As funding for science has declined, scientists have attacked ’ antiscience’ in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University.
Defenders of science have also voiced their concerns at meetings such as "The Flight from Science and Reason", held in New York City in 1995, and
A. confrontation
B. dissatisfaction
C. separation
D. contempt
