Question

[3]. Read the following passage carefully:

Passage: "In a small town, a girl named Meena repaired bicycles in a tiny shed near the school gate. She had learned the work by watching her father, who had repaired cycles for thirty years. When her father fell ill, Meena took over the shed. At first, customers doubted a young girl. They asked for her father and left when they found only Meena. She did not argue. She repaired one puncture so neatly, and fixed one bent wheel so truly, that word spread. Soon, schoolchildren brought their cycles to her before morning assembly. Meena also taught two girls to tighten brakes and oil chains, saying that a skill shared is a skill doubled. When her father recovered, he found the shed busier than before. He told Meena that she had not merely kept his work alive. She had made it larger by sharing it with others." What does Meena mean by saying that a skill shared is a skill doubled?
