Question

Which of the following may not qualify as a falsifiable claim?


Student Answer: Your luck will improve.
Your house will be sold tomorrow.
Granite is more dense than sand.
Smoking may cause heart disease

Answer 1

I am not certain how one could prove the first and the last as true/untrue. The second and third are rather easy to prove/disprove.

Answer 2

the answer is apparently number one, and I choose number three as being not falsifiable. I am currently arguing my point and could use some support. My proof that three of the four claims are falsifiable are as follows. My luck may improve or it may not. I could die immediately after you say the word improve. My house may sell or it may not, and smoking may cause heart diesease or it may not. Seem reasonable so far. Now, we are left with granite, which is clearly more dense than any sand on the face of the earth. What am I missing here. I certainly appreciate your input.

Answer 3

I brought a pair of shoes from that store that immediately fell apart. their shoes are no good. Does this falls under Begging the question fallacy?
