CAT 2 (SC): Created [u]in 1731, Anders Celsius’ original...

[tontonio]

Created in 1731, Anders Celsius’ original thermometer had a scale where the value of 0 corresponded to the boiling point of water; after he died in 1744 the scale was reversed to its present form.
CORRECT B) in 1731, Anders Celsius’ original thermometer had a scale in which the value of 0 corresponded to the boiling point of water; after his death in 1744 the scale was reversed to its present form.

I understand why this answer is correct, however I'm wondering if thermometer doesn't need to be next to its modifying phrase. That's what I initially thought or is it OK just because Anders Celsius’ original further modifies thermometer?

Another way to pur this: I always thought that that was wrong and that the correct answer choice would be something like:
Created in 1731 by Anders Celsius, the thermometer ...

Thanks or your help!

In this sentence, "thermometer" has several modifiers:
"Created in 1731" (WHEN)
"Anders Celsius'" (WHOSE)
"original" (WHICH ONE)

It's always tricky when you have so many noun modifiers that you can't crowd them all right next to the noun. So, yes, it is OK that "Created in 1731" is separated from "thermometer" by "Anders Celsius'", as long as doing so doesn't introduce ambiguity.

Another way to look at it: "Created in 1731" begs the question "WHAT was created?" The answer is correctly found after the comma: "Anders Celsius' original thermometer"

By the way, your suggested phrasing still puts Mr. Celsius in the middle :-)
(Created in 1731) (by Anders Celsius), the thermometer ...
