Question is which is NOT a good technique.
Answer is "B" and here's why:
A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.
B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.

Answer:
There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).
Explanation:
This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.
However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.
