Statements: Jade plant has thick leaves and it requires little water.

Conclusions:

  1. All plants with thick leaves require little water.
  2. Jade plants may be grown in places where water is not in abundance.

A. Only conclusion I follows
B. Only conclusion II follows
C. Either I or II follows
D. Neither I nor II follows
E. Both I and II follow

Answer: Option B

Explanation:

The statement talks of jade plants only and not 'all plants with thick leaves'. So, I does not follow. Also, since jade plants require little water, so they can be grown in places where water is not in abundance. So, II follows.

17. 

Statements: Use "Kraft" colours. They add colour to our life. - An advertisement.

Conclusions:

  1. Catchy slogans do not attract people.
  2. People like dark colours.

A. Only conclusion I follows
B. Only conclusion II follows
C. Either I or II follows
D. Neither I nor II follows
E. Both I and II follow

Answer: Option D

Explanation:

The slogan given in the statement is definitely a catchy one which indicates that catchy slogans do attract people. So, I does not follow. Nothing about people's preference for colours can be deduced from the statement. Thus, II also does not follow.

18. 

Statements: All those political prisoners were released on bail who had gone to jail for reasons other than political dharnas. Bail was not granted to persons involved in murders.

Conclusions:

  1. No political - prisoner had committed murder.
  2. Some politicians were not arrested.

A. Only conclusion I follows
B. Only conclusion II follows
C. Either I or II follows
D. Neither I nor II follows
E. Both I and II follow

Answer: Option A

Explanation:

According to the statement, the political prisoners can be divided into two groups - those who were released and those who were put in jail for political dharnas. However, no person involved in murder was released. This means that no political prisoner had committed murder. So, I follows. Clearly, II is not directly related to the statement and does not follow.

19.

A. Only conclusion I follows
