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.

OA B. I can't understand why a possesive pronoun must be used with a possisive noun ? Because in either case, he clearly refers to him and his still refers to him

This questions tests whether you can spot "pronoun" mistakes.

A)First, "where" is wrong. Second, ...<AC's thermometer>;...<he>.... is wrong. The possessive noun is AC's thermometer. Possessive pronoun can refer back to possessive nouns. But, subject and object pronouns may not refer back to possessive nouns. Therefore, <he> is used incorrectly because it seems to refer back to <AC's thermometer>. The same mistake goes to C.
B correctly this mistake beautifully. The possessive pronoun "his" refers back to "AC's original thermometer". Bull's eye.

D. After semi colon, there should be a sentence, not phrase or clause. Besides, it sounds awkwary.

E. "where" is wrong. Besides, "scale WAS reversed" "was" is needed.

Hope this helps.
