Answer:
If children are inoculated with cowpox taken from the breasts of cattle, they will not develop smallpox.
Step-by-step explanation:
Conditionals describe conditions necessary for something to happen. These sentences consist of two clauses - the main clause, which contains the result, and the if-clause, which introduces the condition. There are four types of conditionals - the zero, first, second, and third conditionals.
The first conditional tells us about things that might happen in the future. The verb of the if-clause is in the present simple tense, and the one in the main clause is in the future simple tense.
In the given example, inoculation with cowpox is the condition, and children not developing smallpox is the result. This means that the given sentence can be transformed like this:
- If children are inoculated with cowpox taken from the breasts of cattle, they will not develop smallpox.
