"The gold key is a pretty horrific symbol of the lengths the government will go to in order to brainwash children into enlisting in the military. They tell them that this key will get them into heaven if they die at war. This harkens back to ancient religious wars, like the Crusades, where dying a martyr was the best possible thing a boy could do. Although, in reality, all it means is that they died as pawns of the government.
This key is an especially repulsive symbol because it holds absolutely no intrinsic value—it's "a plastic key painted gold" (13.34). The Iranian military couldn't even give kids something of value to lure them into war, something they might be able to melt down for money. Of course, what value does money have to a martyr? You can't spend it when you're in the theoretical halls of heaven, with more virgins for the taking than you know what to do with."
Over exaggerated
In the context of this passage, which is talking about how Facebook is attempting to cut down on incorrect, fake, or 'sensationalized' news, the word clearly means news that is not true or over exaggerated in a way that makes it 'click bait'-something that isn't clear, objective content.
They want Horatio to see the Ghost that has been walking at night.
Answer:
Thick segments of tissue would not be enough for Annie Dillard's needs.
Explanation:
When Annie refers to "tissue," she is referring to biological tissues that will be used in the new microscope kit that she received from her parents. For it to be possible for her to visualize biological tissues in this microscope, it is necessary that she has "thin segments of fragile tissue," because thick segments of tissue would not allow a good visualization, with details, in her microscope.
