Answer 1

The two examples of class two levers from the options provided are:

b. bottle opener
d. wheelbarrow

In a class two lever, the load is situated between the effort (force applied) and the fulcrum (pivot point). In the case of a bottle opener, the bottle cap acts as the load, and the fulcrum is where the opener pivots. In a wheelbarrow, the load (material being carried) is between the wheels (fulcrum) and the handles (where the effort is applied).
