[PREMISE]
Out of new printers acquired.
1. twelve percent of laser printers in use had needed servicing on more than one occasion
2.just three percent of inkjet printers that had ever required any servicing at all.
[CONCLUSION]
Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers.
(A) Inkjet printers do not produce noticeably lower print quality than laser printers for standard office documents.
We do not necessarily know if lower quality of print would disrupt workflow. And has nothing to do with serviceability
Therefore eliminated.
B) Offices that use laser printers are not far more likely to operate them at substantially higher print volumes over time than offices that use inkjet printers.
If this option is negated then our conclusion does not hold true.
CORRECT
C) At least as many offices in the survey had acquired laser printers as had acquired inkjet printers.
This is very close.
Lets negate this
many offices in the survey had [NOT] acquired laser printers as had acquired inkjet printers.
This means far few offices had laser printers than inkjet printers.
Does this Break our conclusion
"Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers" ??
It actually strengthens the conclusion EVEN FURTHER.
therefore, eliminated.
D)Laser printers do not generally require longer periods of downtime for each service visit than inkjet printers do.
Negating this,
Laser printers do generally require longer periods of downtime for each service visit than inkjet printers do.
AGAIN, strengthens the conclusion.
Therefore, eliminate.
E) time of acquisition is not necessarily relevant.
