(1) may 18, 2010, marked 30 years since the eruption of mt. st. helens in washington state. (2) the volcano had been assumed to be rather dormant, so the magnitude of the event was surprising, even to volcanologists. (3) predicting an eruption is quite challenging, but there are a number of warning signs. (4) if a volcano is getting close to erupting, the gases it emits will change, as will its pattern of earthquakes. (5) volcanoes may even begin to change their shape as material is moving within them. (6) this happened with mt. st. helens, as it began to bulge visibly from one side.
(7) scientists have a hard time forecasting exactly when a volcano will erupt. (8) often, eruptions aren't accurately predicted because scientists don't have the measurements they need. (9) however, in mexico in 1993, a high level of sulfur dioxide—one of the volcanic gases—was detected around a volcano near mexico city. (10) warnings were issued to the mexican government that an eruption may be looming. (11) it wasn't until many months later that the volcano finally did erupt. (12) scientists say what they most need in order to more successfully predict eruptions is simply more eruptions! (13) that would allow them to test their theories on the real thing.

hello! i am thinking the answer is d. to convince parliament to go to war against nazi germany

sorry if i am wrong

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

the author is showing that it is the insatisfaction of basic needs that brings about the protests such as the strikes.if workers do not earn enough to buy food and feed their families and themselves in order to continue working, what is the use of working? besides, another message from the author is that of the owners of factories should be worried about ensuring their furure by having a second and third generation of workers in their industries.if they do not hear the workers demands, they will not have any more workers to make their pockets full.

the answer is c because info security should not use them for code
