Use a joining word to combine the simple sentences to make a compound sentence.

1/ Jack and the Beanstalk" is a fable. It is very famous.

2/ the beanstalk grew into the sky . Jack climbed it anyway.

3/ Jack climbed the beanstalk . He found a pot of gold.

4/ An angry giant came after Jack . Jack escaped.

The answers:
All sentences use " and"

Two of these sentences would be better if you used but or yet instead of and.

To combine the first two sentences, "Jack and the Beanstalk" is a fable and it is very famous, we can use the joining word "and".

For the next two sentences, "the beanstalk grew into the sky" and "Jack climbed it anyway", we can also use the joining word "and" to form a compound sentence: The beanstalk grew into the sky and Jack climbed it anyway.

Similarly, we can combine the sentences "Jack climbed the beanstalk" and "He found a pot of gold" using the joining word "and": Jack climbed the beanstalk and he found a pot of gold.

Finally, to combine the sentences "An angry giant came after Jack" and "Jack escaped", we can again use the joining word "and": An angry giant came after Jack and Jack escaped.

So, the compound sentences would be:

1. "Jack and the Beanstalk" is a fable and it is very famous.
2. The beanstalk grew into the sky and Jack climbed it anyway.
3. Jack climbed the beanstalk and he found a pot of gold.
4. An angry giant came after Jack and Jack escaped.
