Answer:
A
Step-by-step explanation:
A in this situation is the most logical answer.
Answer B is stating that childhood is not an easy time for every person, the essay states, "But now, I realize that my parents did allow me to have many positive experiences" This excerpt isnt talking about others childhood, but rather HIS own childhood. Though it might be true, it's not the main point.
Answer C says that parents dont express themselves often with their children. Now like answer B, that might be the case in real-life, but it's not what the excerpt is talking about.
Answer D says parents make childhood difficult. Again, might be the case but this excerpt is talking about the opposite thing. "But now, I realize that my parents did allow me to have many positive experiences."
Therefore, its answer A, and because the beginning says, "Looking back at my childhood 20 years later" it just proves further more.
