Answer:
A. makes the issue less abstract
Step-by-step explanation:
Many times in writing or sharing stories with people via physical as well as electronic platforms, people are tempted to think that these stories are purely theoretical or fictional and pose no real significance to their lives. As such, one way to engage the reader is to use real people's stories to explain a controversial issue. This brings the stories down to earth and to the awareness of the reader in more practical ways than before. Suddenly, the reader sees that the issue is not abstract neither is it far-fetched. He is also reminded that this (the issue) can happen to anyone and it is not fiction but a reality.
Hence, using real people's stories to explain a controversial issue makes the issue less abstract
