Question:

Both Henry Cavendish and Johann von Soldner theorized that Newtonian physics predicts that light will bend when passing near a massive object. Two centuries later, Einstein noted that his theory of general relativity predicted that the deflection of light should be approximately double that predicted by Cavendish and von Soldner. Einstein's bold prediction was put to the test in 1919 when observations of the apparent positions of certain stars were made in four cities in South America and Africa during a total solar eclipse. The resulting data were consistent with Einstein's prediction. Subsequent observations made by the Lick Observatory in 1922, the Yerkes Observatory in 1953, and the University of Texas in 1973 were consistent with those made in 1919. What conclusion can be drawn based upon the observations described above?

A The observations are consistent with Einstein's theory of general relativity.
explanation

According to the passage, Einstein's theory of general relativity predicts that light will be bent twice as much by a massive object as was earlier predicted by Newtonian physics. Four scientific observations between 1919 and 1973 recorded data consistent with the results predicted by Einstein. The question asks you to identify a conclusion that can be drawn based upon these scientific observations. Data that are consistent with the predictions of a theory do not prove the theory, although consistent observations that are not explained by the theory can disprove it. The correct answer states that the observations agree with Einstein's theory of general relativity.
