Scientists believe they have discovered the wreck of the USS Harvard, sunk by Japanese torpedoes during World War II. Their conclusions are drawn from underwater searches by mini-submarines of the area about 4 miles of Midway Island in the Pacific Ocean during what started out as offshore oil platform accident procedures. These are some military historians that are skeptical about the scientists'claim, on the basis that sophisticated sonar equipment has not identified the ship as, indeed, the Harvard.


Which of the following, if true, would weaken the historians'arguments?

A) Thorough searching by divers and bathyscopes has not located the wreck.
B) Three other ships were sunk in this area during World War II.
C) The ship's last known position was 20 miles east of Midway
D) The use of sonar only enables the user to identify the shape and dimension of a wreck.
E) It is not known whether the Harvard suffered much structural damage before being sunk.
[Reveal] Spoiler: OA

Strengthens historians claims.

Correct answer as it weakens the historians claim that sonar did not identify the wreck to be USS harward.
E) It is not known whether the Harvard suffered much structural damage before being sunk.
Out of scope.

Could you please let me know how D weakens the historians' claim. Apparently, historians are skeptical about the occurrence of the ship , D seems to be strengthening their claim , shouldn't the and be C.
