2. 2.20 How is an all levels sample obtained?1) 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.
2) b. By blending upper, middle and lower samples from the same tank.
3) 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.
4) 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.

3. 2.37 How is draft defined?1) a. The vertical distance from the surface of the water to the keel of the ship
2) b. The vertical distance from the deck of the ship to the surface of the water
3) c. The vertical distance from the Plimsoll mark to the bottom of the ship
4) d. The vertical distance from the Plimsoll mark to the deck

4. 2.42 What is load on top?1) a. The shipboard practice of collecting water and water and oil mixtures resulting from ballasting and tank cleaning operations (usually in a slop tank) and subsequently loading cargo on top of it and pumping the mixture ashore at the discharge port.
2) b. The act of commingling existing onboard quantity with cargo being loaded
3) c. Answers a. and b. are correct
4) d. Answers a., b. and c. are all wrong

5. 2.15 What is Total Observed Volume (TOV)?1) a. The total measured volume of all petroleum liquids, sediment and water, and free water at observed temperature
2) b. The total measured volume of all petroleum liquids, sediment and water but excluding free water, at observed temperature
3) c. The total volume of all petroleum liquids and sediment and water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
4) d. The total measured volume of all petroleum liquids excluding water and sediment, at observed temperature
