Interference Question

[Umpteenth]

nsc_wa, really, the best thing you can do for yourself is to get into the rule book. Daily. Twice a day. Pick a section and read it. Put it away. Later in the day, read a different section (or maybe the same one again).

Also, when you have a specific question, such as these from the test, go to the Index section of the 2012 ASA Rule Book. You may have to look in as many as 3 or 4 different areas before you find your answer, but you will probably find it. And, that gets you in the book.

Now, after having researched a particular question and being still unsure, come here and create a thread. State the situation, and provide the stance you have come to based on the Rule Book. Then, the rest of the forum can help you out.
