Scientists, like other people, are always pleased to have their own ideas (A)[confirm / confirmed]. So I was gratified by a report which appeared in the August 1963 issue of the Journal of the British Astronomical Association. This report was written by the famous Soviet astronomer, Dr Nikolai Kozyrev, who several years ago discovered evidence in telescopic photographs to support the belief that some of the craters on the moon are sites of presently active volcanoes. When Dr. Kozyrev first published (B)[that / what] he thought he had seen on the moon, his interpretation was doubted by many astronomers in other lands. Subsequently, however, astronomers here have seen color changes (C)[which / where] they, too, believe are signs of continuing volcanic activity on the previously supposed dead body of the moon.
