Regarding the question below, there is no correct answer. I will put comments next to each answer choice.
Children who watch a great deal of television
and their families have a history of near-sightdness will probably require glasses sooner than their peers who are not predisposed to myopia in these ways.
(a) and their families have a history of near-sightedness - IF 2 NOUNS ARE AROUND "AND" THEY FORM A UNIT. THIS MEANS THAT THE CHILDREN WATCH TELEVISION AND THEIR FAMILIES.
(b) whose families have history of near-sightdness -THIS SPEAKS OF TELEVISION WHOSE FAMILIES - WHAT DOES THAT MEAN?
(c) and a history of near-sightness runs in the family - THIS MEANS THEY WATCH TELEVISION AND A HISTORY.
(d) whose families have a history of near-sightness running in them - SEE b ABOVE. ALSO, THE PHRASE "RUNNING IN THEM" IS SUPERFLUOUS (BECAUSE "HAVE A HISTORY" IS ENOUGH) AND UNIDIOMATIC (WE SAY, "NEAR-SIGHTEDNESS RUNS IN A FAMILY," BUT DO NOT USE THE VERB IN THE PROGRESSIVE.
(e) with a history of near-sightness running in the family - THIS MEANS THAT THE CHILDREN WATCH TELEVISION WITH A HISTORY OF .... THE WORD "WITH" COMBINES "TELEVISION" AND "A HISTORY." THIS IS SOMETHING LIKE "I LIKE PIZZA WITH MUSHROOMS."
I hope this helps.
