Explanation

Five educational films A, B, C, D, and E are to be shown to a group of students. The films are to be shown in a particular order, which conforms to the following conditions: 

A must be shown earlier than C.  B must be shown earlier than D.  E should not be the fifth film shown.

A) A, C, B, D, E

B) A, C, D, E, B

C) B, D, C, A, E

D) B, D, E, A, C

****** other explanations****

First E should not be the fifth film shown. so options (a) & (c) not possible. A must be shown earlier than C, so first A and after than C. According to this order options (c) is also not possible. Now take B must be shown earlier than D. so according to this order option (b) cancelled. So option D is only correct.

Explanation

If yesterday was Monday, then:

Explanation

 Chef selects two sets of ingredients Set 1 and Set 2 for cooking, choosing from seven ingredients T, U, V, W, X, Y, and Z. Set 1 will contain four of the ingredients, and Set 2 will contain the other three ingredients. The Chef must select the ingredients for each set according to the following restrictions:

T cannot be in the same set as U.

If X is in Set 2, Z must also be in Set 2.

If Z is in set 1, W must also be in Set 2.

Question:

If T and Z are in Set 2, any of the following ingredients can also be in Set 2 except:

A. X

B. Y

C. U

D. V

Question:

If Z is in Set 1, which of the following must be true?

A. U is in the same set as v

B. W is in the same set as Y

C. T is in set 1

D. V is in set 2

Question:

If X is in Set 2, which of the following must be true?

A. Y is in the same set as Z

B. T is in set 2

C. U is in Set 2

D. W is in set 1

Solution

T and Z are in the same set like 2 then according to the given restriction there is only U which cannot be in same set as T so the first answer you have selected is wrong its U 1) U 2) V is in set 2 ( because V cannot be put in set 1 with Z,W,T/U,X) here Z,W,X should be fixed according to the given restriction. If you put X in set 2 then Z should also be in set 2 so the permanent member of set one according to question 2 is Set 1 ( Z,W,T/U,X) set 2 : ( U,Y,T/U) Question 3) If X is in set 2 then Z must also be in set 2. furthermore, there will be T/U in the set 2. and no more members because set 2 only contains 3 members. Example, set 1 : T/U, V,W,Y set 2 : X,Z,T/U A) condition 1: Y is in the same set as Z, which cannot be true b) T is in set 2, yes but T can be in set 1, so it is not the condition that must be true. c) U is in set 2, yes again U can be in set 1 so it again doesnt meet the "must be true condition" d) w is in set 1, yes this is correct, because if we put w in set 2 then we have to put T and U together which breaks the rule. mostly importantly there should be only 3 members in set 2. so W should be in set 1 along with T or U, V, Y. correct answer is D) W is in set 1

Researcher: Heavily Insulated homes trap radon gas much better than do poorly insulated homes. Therefore, those who live in heavily insulated homes are at greater risk for certain types of brain cancer because evidence shows that those who are being treated for brain cancer have high blood levels of the radioactive compounds that are found in those who are exposed to high levels of radon gas.

Question:

Which one of the following, if true, most underrates the researcher’s argument?

A. Exposure to radiation is known to Ice to an increased incidence of cancer of all kinds.

B. Young people are particularly susceptible to the negative consequences of high levels of radon exposure.

C. Radioactive compounds are used in many cases to help develop an initial diagnosis of medical

D. The most common brain cancer therapy involves radiation and I, cads, to high blood levels of many radioactive compounds
