During some reasearch, I came across a death certificate, which stated the cause of death to be "Poisoning by pentobarbitone and alcohol". This was in 1964. What would this have most likely been prescribed for (was it only availible by prescription in the U.K.) and what would be the effects of taking it with alcohol?

there are 4 ice cream flavours and 6 toppings.
how many sundaes are possible using one flavor of ice cream and 3 different toppings?

I got C(4,1)XC(6,3) = 80

B) how many sundaes are possible using one flavor of ice cream and from zero to six toppings.

I got C(4,1) X 6! not too sure about that one

then finally C) how many different combinations of flavors of 3 scoops of ice cream are possible if it is permissible to make all 3 scopps the same flavor.

Is there any other way of testing whether or not you have a 1944 Steel penny that won't damage the penny. The magnet test doesn't seem to work cause even when I try to get a 2007 penny to stick to the magnet...it won't. So is there some kind of magnet needed? Like power wise or anything like that, if not then I need to know what are other ways of testing the 1944 penny.

The problem seems to grow and grow. When parents begin lobbying that religious beliefs be taught in science classrooms you have to admit the system is failing (has failed) somewhere. It also seems that these people have convinced themselves that creation is true and evolution is false. Not only this they display a fundamental misunderstanding of what evolution really is, lumping things like the big bang into the theory along with statements like "man came from monkeys." It also seems that they are mostly unwilling to accept an actual education on the subject.

How can we educate those who need it so badly?
