Answer 1

Question 1:
The sequence's insert member function normally puts a new item before the current item.
The new item is put at the beginning of the sequence when there is no current item
Answer:
The new item is put at the beginning of the sequence.

Question 2:
difference between the private member variables of the bag and the private member variables of the sequence is that the sequence has one extra size_t variable.
Answer
The sequence has one extra size_t variable.

Question 3:
operations are likely to have a constant worst-case time is insert
Answer:
insert

Question 4:
stack features of C++ Standard Library cab be used by the bag class
Answer:
The C++ Standard Library
