[不定项选择题]根据下面资料,回答题
It was not exactly a perfect night in Washington for Fourth of July fireworks this year, when fog and rain blanketed the sky and made the Independence Day show from the National Mall less impressive than usual to those who had staked out a spot nearby.
But if you had tuned in on Monday to watch the fireworks on PBS or watched it on your cell phone, you might have figured the sky was cloudless and the fireworks were crystal clear. You might also have wondered if someone had removed the scaffolding that has been on the Capitol dome for two years.
But many eagle-eyed viewers suspected something was not quite right, and PBS later admitted as much: It had spliced in firework footage from previous years with live shots.
The show did not inform viewers that they were watching a highlight reel of past colorful explosions. But "Seinfeld" reruns are one thing; fireworks reruns are quite another. And angry viewers vented.
"Because this year′ s fireworks were difficult to see due to the weather, we made the decision to intercut fireworks footage from previous A Capitol Fourth concerts for the best possible television viewing experience," the show′s organizers said Tuesday in a statement. "We apologize for any confusion this may have caused."
One Twitter user said it "could have been announced at the time", while another called it "a deceptive thing to do." A PBS Twitter account cast the decision as "the patriotic thing to do," but viewers were not convinced.
According to the passage, "eagle-eyed viewers" refer to those ___________.查看材料
A.who are able to notice the suspicious points of fireworks that are difficult to find out
B.who are not able to see the fireworks clearly because of bad weather
C.who become aware of things through the senses
D.who observe and comment on something
