During periods of terrorist activity, people in Britain are always being warned to look out for bombs. Any bag or parcel without an owner WAS seen as a risk to the public. Some time ago a cardboard box WAS found at the entrance to Bristol Zoo one day. It was noticed BY a visitor and reported to the director. Clearly, if it was a bomb and it went off, people might BE killed. So army bomb experts WERE called, and the box WAS safely blown up in a controlled explosion. Soon afterwards IT was reported that the box had BEEN left there by a boy wanting to find a new home for his pet rat. He WAS tired of the rat, he explained. The director of the zoo is thought TO be unenthusiastic about looking after people’s unwanted pets. No one knows what the rat would think if it WAS blown up.
