1. Reading.
Read the newspaper article and choose the correct answer (A, B, D or C).

British MPs want to stop fast food companies advertising to pre-school children in reaction to reports about the growing number of obese children in the United Kingdom.
Debra Shipley, the MP for Stourbridge, wants parliament to vote for a ban on the advertisig of high fat, high sugar and high salt food and drink during pre-school children`s telivision programmes.
„Irresponsible food and drink manufacturers try to get to children through televison advertising and clever marketing strategies”, said Ms Shipley.
„Nobody mentions that high fat, high sugar and high salt food and drink can cause obesity and diabetes. My bill will stop these kinds of foods from being pushed on pre-school children who do not understand the nature of advertising”.
Ms Shipley`s bill already has the support of several organisations, including the National Union of Teachers (NUT), whose general secretary said he is „worried because some companies are trying to market their products and exploit schools, pupils and parents”.
Parlament`s health committee has ordered a number of big advertisers to answer accusations of making profits by advertising products that damage children`s health.
