Explanation:

• Respondents are questioned about unfamiliar issues: If respondents don't understand the topic, their answers won't reflect real opinions, lowering accuracy.
• Respondents reached by telephone refuse to participate: Non - participation can create a biased sample (those who refuse might differ from those who participate), reducing accuracy.
• Respondents hide their true opinions: Dishonest responses mean the poll doesn't capture real views, harming accuracy.
• Respondents are selected randomly from a large pool: Random selection is a good practice that helps ensure representativeness and does not reduce accuracy.

Answer:

• Respondents are questioned about unfamiliar issues.
• Respondents reached by telephone refuse to participate.
• Respondents hide their true opinions.
