Over the past number of years we have raised numerous concerns about the very serious question of whether or not this aspect of government is doing its utmost to ensure that the food we eat, the water we drink, the drugs we have to take and the toys we play with are safe beyond a reasonable doubt.
Through the course of over a dozen months, numerous concerns have been raised about whether or not part of the government has been doing its job.
The original statement says that the concerns have been raised "over the past number of years." My statement refers to this period of time as "over a dozen months," meaning over 1 year, but not specifically referring to the multiple years that the original statement does.
