The best way to increase reading comprehension is to read more often.
Reading different types of books, with different subjects and content,
will condition your brain to retain more information over time. This
will also give you the ability to read more quickly.
B. A possessive noun should have its instead of it's (which is a contraction for it is).
For A. Diana is a singular noun and the apostrophe should come after the r instead of after the s.
For C. The duck would've dunked ITS instead of IT'S beak since it is possessive.
For D. You do not need to put an apostrophe since theirs is already a possessive noun.
A. the headings and bullet points help organize the content in small pieces that are easy to take in.
