Answer:
B. To count the number of words read.
Step-by-step explanation:
Reading speed is calculated by counting the number of words read on the page. The formula for calculating the reading speed is dividing the number of words in two lines by two. Then count the number of lines on the page and multiply by the number of words per line. Then calculate how long you read in sixty seconds.
It is important to mark a starting point when checking the reading rate to count the number of words read. Therefore, option B is correct.
