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 bar code usage than one-dimensional bar codes.
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.

The paradox:
We’re told 2D barcodes are better, yet they are used much less than 1D barcodes.
To resolve it, we need a reason why companies still prefer 1D barcodes despite the advantages of 2D.
(A) irrelevant—about stores with no barcodes.
(B) doesn’t explain why 2D usage is low overall.
(C) would make the paradox worse.
(D) irrelevant—consumer scanning isn’t the issue.
Option (E) says:
1D barcodes last longer and have fewer errors.
That gives a strong practical reason for companies to stick with 1D barcodes, even though 2D barcodes have advantages.
Other choices don’t address the paradox directly:
So (E) best resolves the paradox.

The question explains about the two different bar codes that are in use currently. The one dimensional (1D) can be scanned from one direction only, while the two dimensional (2D) barcodes are omni directional, that can be scanned from any direction.
So, this clearly is an advantage from the shop perspective. The author further mentions 2D bar codes store a larger chunk of data than the 1D codes.
The author concludes, despite the advantages, the 2D code is less used than the 1D code.
Let’s look into the options on why such a paradox exists.
A) Many smaller stores do not use bar codes at all because of the expense.
If that’s the case, this contradicts the fact that 1D is used more than 2D codes. Hence, wrong.
(B) For some products, the amount of data necessary to be coded is small enough to fit fully on a one-dimensional bar code.
With a larger space available to use, the 2D has greater space than 1D. Moreover, the cost constraint for storage usage , or performance issues because of storage is not mentioned. Hence, wrong.
(C) Two-dimensional bar codes are, on average, less expensive than one-dimensional bar codes.
The cost factor of 2D codes vs 1D codes is not discussed, doesn’t resolve the paradox on why 1D codes are more popular than 2D codes. Hence, wrong.
(D) Two-dimensional bar codes can also be scanned by consumer devices, such as cell phones.
This option provides a flexibity for the user to know more about the product details and make a more informed choice during purchase. This should have been a supportive factor for 2D codes. This doesn’t resolve the paradox. Hence, wrong.
(E) One-dimensional bar codes last longer and are less prone to error than two-dimensional bar codes.
The durability of the 1D codes, provide us a good supporting reason that it lasts longer and are less prone to error than the 2D codes. Hence , 1D remains a preferred choice for shops compared to 2D. Thus, resolves the paradox on the excessive usage of 1D over 2D. Hence, correct.
Option E
