Question

read the claim below.
digital books are superior to print books.
select the two pieces of evidence that best support this claim.
the first handheld digital books were developed during the 1990s.
for some readers, digital books often cause more eyestrain than print books.
a vast library of digital books takes up only as much space as a single device.
digital books allow users to adjust the size and spacing of type for better readability.

Explanation:

1. The fact that a large digital library only uses the space of one device highlights a key practical advantage of digital books over print books, which require physical storage space proportional to their number.
2. The ability to adjust text size and spacing for better readability is a functional benefit that print books cannot easily replicate, directly supporting the claim of digital books being superior.
3. The development date of handheld digital books is irrelevant to their superiority, and eyestrain is a disadvantage of digital books, so these do not support the claim.

Answer:

C. A vast library of digital books takes up only as much space as a single device.
D. Digital books allow users to adjust the size and spacing of type for better readability.
