1>the French astronomer Jean Picard became the first person to accurately measure the length of a degree of a meridian and used that to calculate the size of Earth.
-lack of tense agreement between 'to measure' and 'used'
-the pronoun 'that' is vague (not clear reference)
2>the French astronomer Jean Picard became the first person to accurately measure the length of a degree of a meridian and made use of it in the calculation of the size of Earth.
-lack of tense agreement between 'to measure' and 'made'
- 'in the calculation of the size of Earth' is awkward and wordy.
3>the French astronomer Jean Picard made the first accurate measurement of the length of a degree of a meridian and used it to calculate the size of Earth.
4>the first accurate measurement of the length of a degree of a meridian was made by the French astronomer Jean Picard, and he used that to calculate the size of Earth.
- passive voice is used
-the pronoun 'that' is vague (not clear reference)
5>the length of a degree of a meridian was first accurately measured by the French astronomer Jean Picard, who calculated the size of Earth with it.
-'first' gives a different meaning (as if : the length was at the beginning measured by ... then something new happen)
- passive voice is used
- comma should be used before 'who'.
IMO C

Dear Friends,
Here is a detailed explanation to this question-
Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that the French astronomer Jean Picard made the first accurate measurement of the length of a degree of a meridian, and he used the measurement to calculate the size of Earth.
Concepts tested here: Meaning + Pronouns + Awkwardness/Redundancy
A: This answer choice suffers from pronoun ambiguity, as the pronoun "that" has no clear antecedent. Further, Option A uses the passive voice construction "became the first person to accurately measure", leading to awkwardness and redundancy.
B: This answer choice uses the passive voice constructions "became the first person to accurately measure" and "made use of it", leading to awkwardness and redundancy.
C: Correct. This answer choice uses the phrase "the first accurate measurement of the length of a degree of a meridian", conveying the intended meaning - that Jean Picard made the first accurate measurement of the length of a degree of a meridian. Further, Option C provides the appropriate antecedent "measurement" for the pronoun "it" to refer to. Besides, Option C is free of any awkwardness or redundancy.
D: This answer choice suffers from pronoun ambiguity, as the pronoun "that" has no clear antecedent. Further, Option D uses the passive voice construction "the first accurate...was made", leading to awkwardness and redundancy.
E: This answer choice alters the meaning of the sentence through the phrase "first accurately measured"; the construction of this phrase incorrectly implies that Jean Picard accurately measured the length of a degree of a meridian for the first time; the intended meaning is that Jean Picard made the first accurate measurement of the length of a degree of a meridian.
Hence, C is the best answer choice.
All the best!
