Why did critics think that venters sequence would be riddled with errors if he used the new method he developed which entailed fragmenting the human genome sequencing the fragments and then aligning the sequence

The cost of the project expected to be high due to generation of sequencing without errors.

Explanation:

Craig venter wanted to show the power of genomics by transforming the health sector. He found that shotgun sequencing was effective to interpret the human genome. But other geneticists denied of using this technique as they though this method is not accurate for interpreting the genome of human population. It is more logistic and requires a significant costs to be paid.  

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
