Answer:
The correct answer is "helping to support their family."
Step-by-step explanation:
In Chapter 3 of "I Am Malala," when Malala went to the dump to throw their rubbish away, she saw several children. Malala's father explained to her that these children were helping to support their families by collecting and selling recyclable materials found in the trash. He mentioned that many families depended on this work to survive and that the children were not causing trouble or spray painting buildings, but rather were doing an important job to make ends meet.
