885 - Logical Reasoning

Question: The increase in the number of newspaper articles exposed as fabrications serves to bolster the contention that publishers are more interested in boosting circulation than in printing the truth. Even minor publications have staffs to check such obvious fraud.
The argument above assumes that

1. newspaper stories exposed as fabrications are a recent phenomenon.
2. everything a newspaper prints must be factually verifiable.
3. fact checking is more comprehensive for minor publications than for major ones.
4. only recently have newspapers admitted to publishing intentionally fraudulent stories.
5. the publishers of newspapers are the people who decide what to print in their newspapers.
