To complete the sentences, we need to carefully match each word with its context. Let's analyze each sentence one by one:
1) It would be a good idea to launch a big __ to promote daily exercise.
The word that fits best here is "campaign." A campaign refers to an organized course of action to achieve a particular goal, in this case, promoting daily exercise.
2) I hope the government doesn't raise income __. Most people already earn too little.
The word "tax" fits perfectly in this context. Income tax refers to the tax levied by the government directly on personal income.
3) I think people should have the __ to choose what they want to eat and drink.
The word "right" is appropriate for this sentence. Having the right means having the entitlement or freedom to choose what one wants to eat and drink.
4) The _____ of the disease is expensive because the medicine costs a lot of money.
In this context, "treatment" fits well. Treatment refers to the medical management and care of a patient for an illness or injury, and it is often costly, especially if it involves expensive medication.
5) Last year our parliament passed a new ___ to make smoking in restaurants illegal.
The suitable word here is "law." A law is a rule made by a government that prohibits or mandates certain behaviors, such as smoking in restaurants.
6) Our school wants to raise ___ of the importance of healthy eating.
Here, "awareness" is the word that completes the sentence. Raising awareness means increasing public understanding and knowledge about a particular issue, in this case, the importance of healthy eating.
The two words that are not used are "diet" and "issue." These words do not fit naturally into any of the provided sentences.
