Comprehension

Hi Please help me with these questions on the passage given below:

“Hurry,” Marcovaldo said to his three boys, “take the jars, go and catch as many wasps as you can.” The boys went off. It was a sunny day, many wasps were buzzing along the avenue. The boys usually hunted them at a certain distance from the tree where their nest was, trying to catch isolated insects. But that day, Michelino, to save time and catch more, began hunting right at the entrance to the nest. “This is the way to do it,” he said to his brothers, and he tried to catch a wasp by putting the jar over it the moment it landed. But, every time, that wasp flew away and came back to light closer and closer to the nest. Now it was at the very edge of the hollow in the trunk, and Michelino was about to lower the jar on it, when he felt two other big wasps fling themselves on him as if they wanted to sting him on the head. He shielded himself, but he felt the *** of the stings and, crying out in pain, he dropped the jar. Immediately, dismay at what he had done erased his pain: the jar had fallen into the mouth of the nest. No further buzzing was heard, no more wasps came out; Michelino, without even the strength to yell, took a step backwards. Then from the nest a thick, black cloud burst out, with a deafening hum: all the wasps were advancing at once in an enraged swarm! His brothers heard Michelino let out a scream as he began running as he had never run in his life. He seemed steam-driven, as that cloud he trailed after him seemed the smoke from a chimney. Where does a child run when he is being chased? He runs home! And that’s what Michelino did. The passers-by didn’t have time to realize what that sight was, something between a cloud and a human being, darting along the streets with a roar mixed with a loud buzz. Marcovaldo was saying to his patients: “Just one moment, the wasps will soon be here,” when the door opened and the swarm invaded the room. They didn’t even see Michelino, who went to stick his head in a basin of water: the whole room was full of wasps and the patients flapped their arms in the futile effort to drive them away, and the rheumatics performed wonders of agility and the benumbed limbs were released in furious movements.
