Read the passage and underline all the subject clauses. Then in pairs, discuss whether the sentences with subject clauses can be paraphrased.
Grandma has been complaining about the vegetables sold in the supermarket, which have been grown using chemical fertilisers. To her, that they look beautiful on the outside is obvious. However, what she is unhappy about is the lower nutritional value and reduced flavour. Now that both of my grandpparents have retired from their jobs in the city, how they are going to spend their retirement is an important decision for them. Whether they can live a healthy life is the first thing they are considering. So they have made up their minds to move to the countryside, where they can live a green life.
