Unlike the original National Museum of Science

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to "touch" each exhibit, which thereby activates the animated functions of the piece.

Hi instructors/experts,

Hi instructors/experts,

I have no idea about B.
IMO, "an activation of... " works as an absolute phrase, describe the proceeding action
"in turn" is a prep, modifier the absolute phrase,

it confused me a lot, it is not absolute phrase in B? why?

please help to clarify my fault

thanks a lot.
have a nice day

Hi Shu Zhang,

Happy to help :) First, "an activation of" isn't considered an absolute phrase, since it does not include a participle. Rather we have a noun "an activation" plus the preposition "of." Also, "in turn" is an idiom that can be used in a formal way to say "as an equal or related effect." The idiom is normally found with verbs to relate two actions. In (B) we would be comparing an action ("encourages visitors") with a noun ("an activation"), which isn't correct.

I hope this helps! :)
