One Class Surveyor got onboard of a 45000 DWT new construction Chemical Tanker a week before delivery， he carried out the initial Safety Equipment survey in accordance with the Fire Fighting and Life-saving Control Plan.Surveyor noted that the vessel had two (2) 15 persons’ Life-rafts at each side， and One (1) 6 persons’ Life-raft on the forward main deck. The surveyor verified the Life-rafts’ certificate and found that the max storing height of one 15 person’s Life-raft at port side to be 18 meters as indicated on its certificate. But the surveyor checked the drawings and noted that actual storing position was 18.5 meters above the Lightweight water line of this vessel.Surveyor recommended shipyard to change the Life-raft or re-locate the life-raft in order to comply with the stowing height requirement as indicated on its certificate. Do you think the Surveyor’s recommendation is correct？（）
A
The surveyor’s comment was not correct； because the Life-raft has the Hydra-Static Releaser， should not care the height of Storing Position
B
The surveyor’s comment was correct； because if the Storing height was over the Limit of the Life-raft， It may damage the Life-raft when throwing off to the water
C
The surveyor’s comment was not correct； the storing position was the same location as showing on the approved drawings
D
The surveyor’s comment was correct； as a surveyor， he can give any comment as he like

A company that makes Computer Assisted Design (CAD) software has, within its application, some utility classes that are used to perform 3D rendering tasks. The company‘s chief scientist has just improved the performance of one of the utility classes‘ key rendering algorithms, and has assigned a programmer to replace the old algorithm with the new algorithm. When the programmer begins researching the utility classes, she is happy to discover that the algorithm to be replaced exists in only one class. The programmer reviews that class‘s API, and replaces the old algorithm with the new algorithm, being careful that her changes adhere strictly to the class‘s API. Once testing has begun, the programmer discovers that other classes that use the class she changed are no longer working properly.What design flaw is most likely the cause of these new bugs?（）A.InheritanceB.Tight couplingC.Low cohesionD.High cohesionE.Loose couplingF.Object immutability
