Two-dimensional bar codes are omni-directional; that is, unlike one-dimensional bar codes, they can be scanned from any direction. Additionally, two-dimensional bar codes are smaller and can store more data than their one-dimensional counterparts. Despite such advantages, two-dimensional bar codes account for a much smaller portion of total barcode usage than one-dimensional barcodes.
Which of the following, if true, most helps to resolve the apparent paradox?
(A) Many smaller stores do not use bar codes at all because of the expense.
(B) For some products, the amount of data necessary to be coded is small enough to fit fully on a one-dimensional bar code.
(C) Two-dimensional bar codes are, on average, less expensive than one-dimensional bar codes.
(D) Two-dimensional bar codes can also be scanned by consumer devices, such as cell phones.
(E) One-dimensional bar codes last longer and are less prone to error than two dimensional bar codes.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."
"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."
"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
