Example Argument: There are a lot of gray clouds outside. So it's going to rain today.
Analysis: What would make this argument strong or valid is knowing the weather from something like the news or newspaper or actually feeling some rain drops. If left as is, it would be a very weak argument because gray clouds do not necessarily mean that it is going to rain. It could just be a really cloudy day. If the argument said, "There are a lot of gray clouds outside. The weather report said that there is a 100% chance of showers. So it's going to rain today." then the argument would be good because of that extra premise. The first premise about the gray clouds could therefore be removed as the second premise would suffice.
"The weather report said that there is a 100% chance of showers. So it's going to rain today.", would be the better, stronger argument.
