 Question 1
Â
Â
Which of the following statement(s) is (are) TRUE regarding the impact of uncertainty and data quality?
Â
 |  |
Uncertainty stems from both natural variability and lack of knowledge. |
 |  |
Studies have shown that a high degree of uncertainty has relatively little impact on an overall exposure assessment. |
 |  |
Significant gaps in data will not affect the effectiveness of risk communication. |
 |  |
The contribution of variability-driven uncertainty is usually larger than that of lack-of-knowledge uncertainty. |
Â

Question 7
1.     Â
Â
