Why? a. Anna b. Thomas c. Lara d. David e. Karen

Explanation / Answer

18 ) I and III only
Reason : I : Iterator is declared with person.iterator()
Checks if nexts elements are present using it.hasNext()
Increments next using it.next();

Same with III as well

For II : we declare iterator as person.get(0) it doesn not return an itertor hence false


19) (c) Lara

Reason we do it.next() thrice and it points to David which is removed hence it now hold Lara
