Which sentence does not have faulty parallelism? a. a high-fiber diet allows the dieter to eat unlimited amounts of many green vegetables, but eating very little in the way of starches such as potatoes. b. because of several planks that need to be replaced, it is not safe for guests to walk on, around, or stand near the wooden bridge. c. james bond embodies the ideal playboy of the 1950s and 1960s: tough, sophisticated, and women can't resist him. d. the new system will enable teachers to keep a running total of each student’s test scores, factor in attendance as part of the final grade, and calculate each student's class standing throughout the semester.

The answer is D.

"Keep", "factor", and "calculate" are all verbs in the list of things the new system allows teachers to do. The other sentences are inconsistent with their list of verbs/adjectives/nouns. Thus, option D is the only one that is grammatically correct.

I am not too good at explaining, so let me know if you are still confused.

Hope this helps! :)

The correct answer is D. The new system will enable teachers to keep a running total of each​ student’s test​ scores, factor in attendance as part of the final​ grade, and calculate each​ student's class standing throughout the semester. Faulty parallelism is the construction of the sentence in two or more parts all equivalent in meaning but not grammatically similar in form.
