Weaken
A group of dedicated amateur astronomers has evaluated the new Orion refractor telescope. They found that it allowed them to see planetary details clearly, which were previously only visible as blurred images through their 10-inch (approximately 25-centimeter) Schmidt-Cassegrain telescopes, despite the 10-inch telescopes having larger apertures that collect more light than the 5-inch (approximately 12.5-centimeter) Orion. Based on these findings, any serious amateur astronomer should choose the Orion if they are purchasing a telescope for planetary observation. Which one of the following most seriously weakens the argument?
