1. Define uranium-enrichment from para. 1 and sanctions as used in para. 3.

2. What revelation did Iran make in a letter to the IAEA this week?

3. Why has the U.N. Security Council already imposed three sets of sanctions on Iran?

4. Why does the international community fear that the Iranian government will use their nuclear technology to make nuclear weapons?

5. a) What is the purpose of the Oct. 1 talks between Iran and the five permanent U.N. Security Council members and Germany?
b) How has Iran already responded to these future requests?

6. Read the "Background" below.  U.N. officials familiar with the IAEA's attempts to monitor and probe Iran's nuclear activities have previously told the AP that they suspected Iran might be running undeclared enrichment plants. The previous three sets of sanctions against Iran have not been effective in persuading them to end their nuclear program. The U.S. and others say they will now give Iran until December to comply or face further sanctions. How effective do you think these further sanctions will be? How should the international community deal with Iran at this point? Be specific.
