SAT语法部分求助
1.The decline in science education during the period had two causes:less funding for scientific research with a decrease in jobs related to space and defense.
（为什么是with a decrease这个部分错了?）
2.The new system,which uses remote cameras in the catching of speeding motorists,may undermine the police department's authority.
（为什么是in the catching of这个部分错了?）

第一题：应为前面说the decliine in science educaion有两个原因,所以后面相应的也应该有两个解释.也就是说冒号后的部分应该有并列的东西来解释the decliine in science educaion.根据题目的原意,应该是less funding for scientific research and a decrease in jobs related to space and defense.即把wih 替换成and.
第二题：应该把in the caatching of改成to吧
新的系统运用遥感相机来照下超速的motorists
