Let's analyze the statements one by one:

1. 7∈A: This statement means "7 is an element of set A." Looking at set $A = \{1, 2, 3, 4, 5, 8\}$, we see that 7 is not an element of set $A$.
   Result: False

2. B⊂A: This statement means "B is a subset of A." A set $B$ is a subset of $A$ if every element of $B$ is also in $A$. Looking at set $B = \{1, 2, 8\}$ and set $A = \{1, 2, 3, 4, 5, 8\}$, we see that all elements of $B$ (1, 2, 8) are in $A$.
   Result: True

Would you like further details or have any questions?

Here are 5 related questions to deepen understanding:

1. What is the difference between a subset and a proper subset?
2. Can a set be a subset of itself? Why?
3. What is the complement of set B with respect to set A?
4. How can we determine the union of sets A and B?
5. What does the intersection of A and B look like?

Tip: When verifying if one set is a subset of another, check if every element of the smaller set appears in the larger set.
