Accepted Answer

### Question 1
# Brief Explanations:
Oceans cover about three - quarters (75%) of the Earth's surface. So the correct option is the one with "three - quarters".
# Answer:
c. three - quarters

### Question 2
# Brief Explanations:
The correct amount of plastic that ends up in the oceans every year is 6,000,000 metric tons. This is a known fact about plastic pollution in oceans.
# Answer:
d. 6,000,000

### Question 3
# Brief Explanations:
Plastic is not biodegradable in the traditional sense (it breaks down into microplastics over a very long time, not like organic matter). So the statement "Plastic is biodegradable" is false.
# Answer:
b. False

### Question 5
# Brief Explanations:
"Junk Beach" is located in Hawaii. This is a specific location related to plastic pollution in the ocean context of the documentary.
# Answer:
b. Hawaii

### Question 6
# Brief Explanations:
A large system of rotating ocean currents is called a gyre. Whirlpool is a small - scale vortex, jet stream is in the atmosphere, and cyclic tide is not the term for ocean current systems.
# Answer:
a. gyre

### Question 8
# Brief Explanations:
Scientists estimate that up to 20,000 metric tons of plastic enter the oceans daily. This is a key statistic about daily plastic pollution in oceans.
# Answer:
c. 20,000

### Question 9
# Brief Explanations:
The two explored trash vortices are the Great Pacific Garbage Patch (North Pacific Gyre) and the South Pacific Gyre (or also the North Atlantic Gyre can be considered, but one common explored one is the Great Pacific Garbage Patch (associated with the North Pacific Gyre)).
# Answer:
Great Pacific Garbage Patch (or North Pacific Gyre, or South Pacific Gyre, or North Atlantic Gyre - any one of the explored trash vortices)

### Question 10
# Brief Explanations:
When scientists initially pulled their net behind their boat in the South Pacific Gyre, plastic was found. So the answer is yes.
# Answer:
a. Yes

### Question 11
# Brief Explanations:
Jan Andries Van Franeker's research showed that almost every bird examined in Northern Europe had plastic in its stomach. So the statement is true.
# Answer:
a. True

### Question 12
# Brief Explanations:
When a bird's stomach contains less than 10 plastic particles, the ocean is considered clean according to the context of the documentary.
# Answer:
b. 10

### Question 13
# Brief Explanations:
Colors like red and yellow (or also white) are more likely to be consumed by animals like birds as they may resemble food sources (like small organisms) to the birds.
# Answer:
Red (or Yellow, or White - any one of the colors that resemble food to birds)

### Question 14
# Brief Explanations:
The idea that plastic is clean and safe is false because plastic is a major pollutant, contains toxins, and harms marine life and ultimately human health.
# Answer:
b. false

### Question 15
# Brief Explanations:
One toxin found in the world's oceans is mercury (or also PCBs - Polychlorinated Biphenyls, or DDT). These toxins accumulate in the ocean environment.
# Answer:
Mercury (or PCBs, or DDT - any one ocean - based toxin)

### Question 16
# Brief Explanations:
Toxins in water are absorbed by small marine organisms (like plankton). These organisms are eaten by larger organisms (like small fish), which are then eaten by bigger fish or marine animals. Humans eat these fish/marine animals, and thus the toxins are passed up the food chain to humans. Also, toxins can attach to plastic particles, which are eaten by marine life, and when humans consume these marine life, the toxins enter the human body.
# Answer:
Toxins in water are taken up by plankton. Small fish eat plankton, larger fish eat small fish, and humans eat fish. Toxins accumulate up the food chain (biomagnification) and reach humans. Also, toxins on plastic particles are ingested by marine life, and when humans eat those marine life, toxins enter humans.
