Very good!

Couple small grammar and spelling mistakes... for example this sentence.

"The author should provides the imformation about the sample, we don’t know where are the cans from and when do they product, perhaps the sample comes from nationwide or just only a local, the two statistics does not necessarily apply to each other, so the survey results are not reliable."

Phrased with more accurate grammar might look like this.

"The author should provide information about the sample, we do not know where are cans came from and when they were produced, perhaps the sample came from across the nation or perhaps they were local, the two statistics would not necessarily apply to each other, so the survey results are not reliable."

I only noticed a couple spelling mistakes

bravo keep up the good work
