question 5\nthe artisans of the igun eronmwon guild in benin city, nigeria, typically ______ the bronze - and brass - casting techniques that have been passed down through their families since the thirteenth century, but they dont strictly observe every tradition; for example, guild members now use air - conditioning motors instead of handheld bellows to help heat their forges.\nwhich choice completes the text with the most logical and precise word or phrase?\na) experiment with\nb) adhere to\nc) improve on\nd) grapple with
Answer
Brief Explanations:
The text mentions that the artisans have been passing down techniques since the 13th - century and then gives an example of not strictly observing every tradition. "Adhere to" means to follow or stick to something. It makes the most sense as they typically follow the traditional casting techniques but don't follow all traditions strictly. "Experiment with" implies trying new things which isn't the main idea here. "Improve on" suggests making the techniques better which isn't indicated. "Grapple with" means to struggle with or try to deal with, which doesn't fit the context.
Answer:
B. adhere to
