a)
- It must be a mosquito; the man might be trying to kill it; he can't have killed it, as it's still buzzing.
- The man could have been robbed; someone might have stolen his phone; it's unlikely that the police will catch the thief.
- The couple are probably arriving home; the noise could be a burglar; they must have left the cat inside / the window open.
b)
- The man is asleep, is woken up by a mosquito, sprays the room, then whacks it with newspaper and thinks he's killed it. He goes back to sleep, the mosquito appears again; this time he gets it.
- Someone grabs the man's bag in the street and runs off, gets onto a scooter / motorbike, drives off but crashes, the police arrive and give the man his phone back.
- A man and a woman arrive home late at night and hear a noise as if someone is in the house; they open the door and find it's the cat
d)
This photo was taken in Sendai, Japan. Chacha, a 24-year-old male chimpanzee, had escaped from the zoo. After two hours, he was found near some houses, climbing on power lines. Eventually, he was captured and returned safely to the zoo.
