(1) 有一个set S with positive integerK, K>1. Two numbers can be divided byany K in set S. one of these two numbers is 2^2*3^2*5^4*11*13, the other is3^5*5^7*7^3. How many numbers are there in set S?

(2) DS: Someone invested X dollarin an account A with simple annual interest, interest rate is r%; he alsoinvested Y dollar in another account B with simple annual interest, interestrate is t%. After one year, is the total interest earned from account A greaterthan the total interest earned from account B?
(1) 0<x<y<2x
(2) 0<2r<t
My answer is C
(3)DS: One positive integer N, is Mod(N, 10) = 5 ?
(1) Mod(N^2, 5) =0; (2) Mod (N^2,4) =1
I forgot what I selected. Sry.
(4) Someone found that investmentreturn after year t is At= 3/2 At-2 –A t-1 +1, and A1=1, A0= 0, what’s the investmentreturn after 3 years?
My answer is 3.75.
(5) DS: two numbers x and y,0<x<y, is x>10?
(1) 1/x + 1/y = 1/5
(2) 1/x <1/10
My answer is D
(6) five marks, one of them isred. Mary has to be one the red mark, other four students can be on any of themarks. How many way you can put all the students on the mark?

(1) One said: we’ve learned all the possiblelanguages in the history combined. And we know that on language communication systemsamong animals is combinatory language. So no language communication systemamong animals is natural language. What’sthe assumption one made?

My answer is “Every natural language iscombinatory language”

我的verbal不是很好, 先这样吧, 如果想到再放狗狗. 再次感谢.

貌似是狗狗滴83变体吧楼主有没有把什么单词记错呢我看着怎么做不出答案捏也许是我太弱了请楼主赐教

洛计的wording 不是100% original, 第一句不太记得, 因为做的时候觉得跟题目没关系. 我的verbal也不是很好, 我当时的理解是, 就看最后两句好了. orz.... 我对不起大家, 有个typo. (早上醒来就赶快来放狗狗, 估计没睡醒......)
后面两句是: And we know that NO language communication systems among animals is combinatorial language. So no language communication system among animals is natural language. What’s the assumption one made?

My answer is “Every natural language is combinatorial language”

特意跑去看了洛计狗狗的83题, 题目的结构跟那个题目很类似. 看起来只是换了其中的形容词而已. >95% 确定最后两句的wording. 再次对不起.....
