Jane drinks 4 cups of coffee every day. Thus, Jane must have trouble sleeping at night.

The above conclusion relies on which of the following assumptions?

Well done!

This is the author's **assumption** - it explains why the author concluded drinking four cups every day means Jane must have sleeping problems.

Did you use the Work Order in this question?

Incorrect.

The fact Jane finds tea conducive to her sleep is meaningless to the argument. It does not explain why the author concluded drinking four cups every day means Jane must have sleeping problems.

[[snippet]]Incorrect.

The fact Jane goes to bed at 22:00 is meaningless to the argument (be careful not to combine it with answer choice A!). It does not explain why the author concluded drinking four cups every day means Jane must have sleeping problems.

[[snippet]]Incorrect.

The fact Jane drinks four cups of tea a day as well may serve as another **premise** supporting the **conclusion**. However, it is not the author's **assumption**, i.e., it does not explain why the author concluded drinking four cups of coffee every day means Jane must have sleeping problems.

Incorrect.

The fact Jane drinks coffee at night may serve as *another* **premise** supporting the **conclusion**. However, it is not the author's **assumption**, i.e., it does not explain why the author concluded drinking four cups every day means Jane must have sleeping problems.

Great.

You can continue to brush up your Work Order when you approach the upcoming questions.

Using the Work Order may not seem important at the beginning, but it will certainly become crucial as the difficulty level rises, so make sure you remember the steps and how to implement them.
