Question Description
Read the following 1 Passage and answer the items that follow. Your answers to these items should be based on the passages only.Recently some scientists have concluded that meteorites found on Earth and long believed to have a Martian origin might actually have been blasted free of Mars’s gravity by the impact on Mars of other meteorites. This conclusion has led to another question whether meteorite impacts on Earth have similarly driven rocks from this planet to Mars. According to astronomer S. A. Phinney, kicking a rock hard enough to free it from Earth’s gravity would require a meteorite capable of making a crater more than 60 miles across. Moreover, even if Earth rocks were freed by meteorite impact, Mars’s orbit is much larger than Earth, So Phinney estimates that the probability of these rocks hitting Mars is about one-tenth asgreat as that of Mars’s rocks hitting Earth. To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions. He found that 17 of the 1,000 particles would hit Mars.Q.According to the passage, which of the following events may have initiated the process that led to the presence on Earth of meteorites from Mars?a)A meteorite struck the Earth with tremendous velocity.b)A meteorite collided with Mars.c)Approximately 1,000 rocks were ejected from Mars.d)The orbits of Earth and Mars brought the planets to their closest points.Correct answer is option 'B'.
