[originaltext] At a vast dumpsite in the west of Ghana’s capital Accra, smal

At a vast dumpsite in the west of Ghana’s capital Accra, small fires burn among piles of old computers, television screens and laptops, throwing clouds of thick black smoke into the air.
Around them workers pick out motherboards, valuable metals and copper wires, burning away the plastic coverings as they go---filling the air with poisonous fumes. For many it’s a profitable business in a country where nearly a quarter of people live below the poverty line. "It’s an instant job," said Sam Sandu, a scrap dealer who works on the site. "Today you work on it, and you can get your money the same day." But experts warn the poisons present in the waste are slowly harming the workers, as well as spreading pollution into the soil and atmosphere.
Question 3 and 4 are based on the news report you have just heard.
