已知X=21，Y=15，Z=22，计算表达式（（X>Y）or（Y>Z））and（（X<><>

假定用x代表二进制数1010B，用y代表二进制0110B，若x与y通过逻辑运算后得到的结果是1100B，则以下选项中能实现这一逻辑运算功能的算式是（）。（提示：AND代表逻辑乘，OR代表逻辑加，NOT x代表对x逻辑取反）

设x=4，y=8，z=7以下表达式的值是 x＜y And(Not y＞z) Or z＜x

设x=4，y=8，z=7，以下表达式的值是 x＜y And(Not y＞z) Or z＜x

设x=4，y=8，z=7，以下表达式的值是 x＜y And (Not y＞z) Or z＜x

Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

A salvor may be（）the whole or part of the payment due under Salvage Convention to the extent that the salvage operations have become necessary or more difficult because of fault or neglect on his part or if the salvor has been guilty of fraud or other dishonest conduct.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

●设AND、OR和NOT分别表示按位与、按位或和按位求反运算，且X=10011011，Y=01111010，Z=11101000，则(NOT(X) AND Y)= (9) ， (Y OR NOT(Z))= (10) 。10011011011110101110100001100000(10)

设x=4,y=8,z=7，以下表达式的值x>y Or z是 （ ）。
