Question

review the fourth paragraph.
many contemporary halloween traditions can be traced back to the celtic samhain festival and all hallows eve. these include holding parades, playing scary pranks and tricks, bobbing for apples, and lighting bonfires. the popular custom of dressing in costume also came from the celts. they believed that the ghosts of the departed would roam the fields and roads near their homes on this night. afraid of encountering these otherworldly beings on their way to and from the celebrations, the celts began to wear masks and other ghostly gear. this was meant to fool the spirits into believing that the festival attendees, too, were from the spirit world.
ancient celts and contemporary americans are not the only people with
which of the following would be most relevant to add to the fourth paragraph?
how the practice of bobbing for apples came about
how halloween costumes have evolved to the present day
specific examples of the kinds of masks the celts wore

Explanation:

The fourth paragraph focuses on the origin of contemporary Halloween traditions from Celtic Samhain festival, especially the costume - wearing custom. The first option about bobbing for apples is just a listed tradition without further exploration in the paragraph. The third option about specific mask types is too narrow and not in line with the paragraph's focus on the origin and general idea of costume - wearing. The second option about how Halloween costumes have evolved to the present day can extend the discussion on the costume - wearing tradition (which started with Celts wearing masks) and is relevant as it connects the origin (Celtic) to the contemporary (evolution to present - day costumes).

Answer:

how Halloween costumes have evolved to the present day
