2. The street party is a popular form of (1) celebration in Britain. Whole streets come together to mark such important (2) national occasions as a new millennium. Clearly it is (3) impossible to hold a party in a busy street, so traffic is banned. This may annoy motorists but it is (4) unavoidable.

However, although all vaccines produced so far have shown good results on monkeys their (4) effectiveness in tests on humans was far less (5) impressing.

Everybody is then (10) patiently waiting for good news about (11) successful trails of a new medicine as the future costs of malaria spreading are indeed (12) unpredictable.
