    d. The total volume of all petroleum liquids and sediment and water and free water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
3. 2.38 How is trim defined?
    a. The same as the draft
    b. The difference between the forward and aft draft
    c. The average of the forward draft, the amidships draft, and the aft draft
    d. The leaning of the vessel to one side
4. 2.08 What is clingage?
    a. The wedge shaped volume of oil remaining in a tank after discharge
    b. The non-liquid wedge-shaped volume of oil remaining in a tank after discharge
    c. The cargo that adheres to the internal vertical surfaces of a tank after it has been emptied.
    d. The ability of a liquid to cling to the inside surface of a container
5. 2.20 How is an all levels sample obtained?
    a. By submerging an unstoppered sampler to a point near the tank draw-off outlet (suction) level and then raising it, all at a uniform rate, so that it is no more than 85% full on emerging from the liquid.
    b. By blending upper, middle and lower samples from the same tank.
    c. By submerging a stoppered sampler to a point as near as possible to the draw-off outlet (suction) level, then opening the sampler and raising it at a rate such that it is no more than 80% full as it emerges from the liquid.
    d. By submerging a stoppered sampler to the mid point of the product in a tank, then opening the sampler and raising and lowering it at a uniform rate until the sampler is full.
6. 2.19 What is Total Calculated Volume (TCV)?
    a. GSV plus free water
    b. NSV plus free water
    c. GSV less sediment and water
    d. NSV plus sediment and water
7. 2.21 How is a running sample obtained?
    a. by lowering an unstoppered sampler from the top of the oil to the level of the outlet (Suction) and returning it to the top of the oil at a uniform rate so that the sampler is no more than 85% full when withdrawn from the oil.
    b. by lowering a stoppered sampler to the level of the outlet, then opening the sampler and raising it at a uniform rate so that it is about 80% full when withdrawn from the oil.
    c. by lowering a stoppered sampler to the mid point of the tank contents, then opening the sampler and raising and lowering it at a uniform rate until it is full
    d. by lowering an unstoppered sampler to the mid point of the tank contents, then raising and lowering it at a uniform rate until it is full
8. 2.11 What is the formula for density?
    a. Length divided by width
    b. Volume divided by temperature
    c. Mass divided by volume
    d. Mass divided by relative density
9. 2.37 How is draft defined?
    a. The vertical distance from the surface of the water to the keel of the ship
    b. The vertical distance from the deck of the ship to the surface of the water
    c. The vertical distance from the Plimsoll mark to the bottom of the ship
    d. The vertical distance from the Plimsoll mark to the deck
10. 2.17 What is Gross Standard Volume (GSV)?
    a. The total volume of all petroleum liquids excluding free water, water and sediment, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
    b. The total volume of all petroleum liquids including free water, water and sediment, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
    c. The total volume of all petroleum liquids and sediment and water, excluding free water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
    d. The total volume of all petroleum liquids including free water but excluding sediment and water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
