I am selling 4 of our old BenQ 6100 series projectors that we used in our business . The projectors are in great working condition however we had too much ambient light and had to upgrade to some projectors that were brighter . These however will work well in a room that has little to no outside light .

Question: Why is the writer selling 4 projectors ?
Answer: Because they are not being used anymore .Because they were used in a business .None of the above choices .Because the projectors are in great working condition .
