OVERCOMING A CHALLENGE AND WHAT I LEARNED
Last week, there was a fire at home which was caused by an electrical spark.
Within minutes, there was thick smoke and a fire which had already consumed some chairs, I was alone with my four-year-old brother so I panicked and started looking for him and in my panic, I completely forgot where his room was, fortunately I heard his cry and located him, then took him out of the house and called the fire department.
It was a scary moment for both of us, and I'm grateful that the fire did not cause an explosion and the fire was contained by the firefighters as soon as they arrived.
I learned that I need to stay calm especially in situations like that because it takes a cool head to think clearly and rationally. My panic caused delay in finding my brother which made him inhale poisonous smoke and required hospitalization.
I think it is b. hope this helped
