In 1912, Austrian physicist Victor Hess ascended in a balloon to measure radiation levels at high altitudes, expecting them to decrease. Instead, he discovered that ionizing radiation actually increased with altitude. Hess proved that radiation did not emanate from the Earth itself, which was a hypothesis that had been proposed by earlier scientists, but instead, it came from outer space.
Which choice most effectively and concisely expresses the information in the underlined portion of the sentence?
- ANO CHANGE
- Hess proved that radiation came from outer space rather than from the Earth, as earlier scientists had hypothesized.Cevap
- CHess proved that radiation came from outer space rather than from the Earth, this was hypothesized by earlier scientists.
- DHess proved that radiation came from outer space rather than from the Earth, a hypothesis, that earlier scientists had proposed.
Cevap
Hess proved that radiation came from outer space rather than from the Earth, as earlier scientists had hypothesized.
The correct choice is the most concise option that preserves the original meaning and is grammatically correct. It eliminates the wordy passive clause ('which was a hypothesis that had been proposed...') and uses the active and direct phrasing 'as earlier scientists had hypothesized' to contrast with Hess's findings.
