Single correct option
Read the passage and answer the question that follows.
Ghost nets — commercial fishing nets lost, abandoned or discarded at sea — continue to trap and kill marine life for years or even decades after the boat that owned them has moved on. [1] Unlike a net actively being hauled in, a ghost net drifts with no one to release entangled animals, so a single net can accumulate an indiscriminate toll of fish, turtles and seabirds over its entire drifting lifespan. [2] Estimates of how many nets are lost each year vary enormously depending on the region and gear type studied, which has made the true scale of the problem difficult to pin down with confidence. [3] Several coastal nations have begun requiring gear-marking, so that a net's owner can be identified and, in principle, held responsible for its recovery. [4]
Where would the following sentence best fit?
'This uncertainty has not, however, stopped some marine biologists from calling ghost nets the single most lethal form of ocean plastic per tonne, given how efficiently they continue to entangle after being lost.'

Where would the following sentence best fit?
'This uncertainty has not, however, stopped some marine biologists from calling ghost nets the single most lethal form of ocean plastic per tonne, given how efficiently they continue to entangle after being lost.'
- A. Position 1
- B. Position 2
- C. Position 3
- D. Position 4
Show answer and solution
Answer: (C) Position 3
The new sentence begins 'This uncertainty has not, however, stopped...', which requires an immediately preceding statement about uncertainty — supplied by the sentence at position 3 about estimates varying and the scale being 'difficult to pin down with confidence'. It must come before the shift to policy response at position 4 ('Several coastal nations have begun requiring gear-marking'), since that sentence moves to a different topic (remedies) rather than continuing the discussion of scale/lethality. Positions 1 and 2 precede any mention of uncertainty, so 'this uncertainty' would have no antecedent there.
