Explanation:



The predicate F(x, y, t) represents the statement that person x can fool person y at time t. Here, x, y and t are variables. This means that the statement can be true or false based on what values are assigned to x, y and t.



Now, let's look at the given formula xyt(F(x, y, t)). This formula is saying that there exists some value of x, y and t such that F(x, y, t) is true. In other words, there exists a person x who can fool a person y at time t.



Let's analyze each option to see which one expresses the meaning of the formula best.



Option A: Everyone can fool some person at some time


This option is saying that for every person x, there exists some person y and some time t such that x can fool y at time t. This is not equivalent to the given formula because the formula only says that there exists some value of x, y and t such that x can fool y at time t. It does not say that this is true for every x, y and t.



Option B: No one can fool everyone all the time


This option is saying that there does not exist a person x who can fool every person y at all times. This is equivalent to the given formula because the formula is saying that there exists some value of x, y and t such that x can fool y at time t. This means that there does not exist a person who can fool every other person at all times.



Option C: Everyone cannot fool some person all the time


This option is saying that for every person x, there exists some person y and some time t such that x cannot fool y at time t. This is not equivalent to the given formula because the formula only says that there exists some value of x, y and t such that x can fool y at time t. It does not say that this is false for every x, y and t.



Option D: No one can fool some person at some time


This option is saying that there does not exist a person x who can fool some person y at some time t. This is not equivalent to the given formula because the formula is saying that there exists some value of x, y and t such that x can fool y at time t. It does not say that this is true for every x, y and t.



Therefore, option B is the best expression of the given formula because it is equivalent to the formula.
