Explain the concept of an unreliable narrator.
An unreliable narrator, seen in books such as Life of Pi, is one who the reader cannot trust. The narrator will often tell the story, and then give a different version of the story at some point. These versions are often left open-ended, with no answer as to which version is the correct one.
Subject: Basic Chemistry
Explain the difference between a cation and an anion.
Cations are positive ions (remember, cats have paws, so they are paws-itive). Cations LOSE negatively charged electrons, and thus have positive charges. Anions are negative ions. Anions GAIN negatively charged electrons, and thus have negative charges.
What is the difference between these two sentences: 1. We invited two cats, Lucy, and Irene. 2. We invited two cats, Lucy and Irene.
The Oxford comma. In the first sentence, the use of the Oxford comma indicates that four individuals were invited: two cats, and Lucy and Irene. In the second sentence, the lack of the Oxford comma indicates that only two cats were invited, whose names were Lucy and Irene.
