Answer:
One way of helping other people is to donate your clothes to the poor. For instance, I brought my old clothes to an orphanage. The teenage girls who live there with no support from their parents really appreciated it. On the other hand, I did not need these clothes anymore, and by donating, I made more space in my wardrobe. The whole experience was really rewarding, as it is very fulfilling to help those in need. Another way of helping people is to donate food to the poor or money to the sick who cannot afford therapy.
A is the most common but it depends on what the sentence is
A river. People describe a river as "running water". The mouth is the opening or beginning, and the riverbed is the shore.
Nice riddle.
