Because Emnie lends Alfonso his bike, Alfonso offers to do the dishes for Emnie.
Answer: Option 3.
Step-by-step explanation:
The theme "by helping others, we help ourselves" means that if we decide to help others, others will also help us in return. So what we do others, they will also do for us. The favor is returned back to us.
It is proved in the sentence that since Emnie has decided to lend Alfonso his bike which is a great help to Alfonso, Alfonso also in return helps Emnie in washing her dishes. Therefore the work load of Emnie also reduces. So this proves that if we help others, others will also return the favor by helping us and reducing our work load, which means we help ourselves.
