Task 1. Read the text and answer the questions. Fast food is the food of the future
It is difficult to imagine our life without fast food. It is gradually forcing out the traditional cuisine,
and many people are sure that fast food will dominate in the future. In my opinion, fast food is
really the thing of the future. First of all, people's life is getting faster, and in the future it will reqire
much quicker solutions in almost every sphere. People will have to do things more quickly, including
meals. The schedule of most people is becoming tougher, so, eventually, they will not have enough
time to eat properly. Fast food will be the best suited for a quick meal. Sandwiches and burgers of
various kinds are advertised and sold on every corner, so people cannot resist a temptation of
buying one. In the future, the temptation will definitely grow on. But there are people who believe
that fast food will never dominate home-cooked meal because of its harm to the health. It is
common knowledge that this kind of food causes serious illnesses, because it is made mostly from
artificial substances. Never the less I cannot support the opposing opinion because food production
is being perfected at a high rate, and future fast food is overwhelmingly likely to consist of healthy
ingredients. In conclusion, I would like to emphasize the fact that the future is born in the present. If
we want to predict what our life will look like in the years to come, we should pay attention to the
modern tendencies. As regards our meal, fast food is booming today, which means it will be our
basic food tomorrow.

Определи верный ответ на вопрос.

Почему пастушью сумку, дикую редьку, горчицу относят к семейству крестоцветных (капустных)?

Потому, что эти растения:
