- CAll hockey players play football
- DAll football players play hockey.
Solution & Step-by-step Explanation
Football Players and Logical Deduction
The question presents two statements about sports players and asks us to identify the logical conclusion that follows from them. This type of problem tests our ability to apply deductive reasoning and understand the relationships between different groups of players.
Analyzing the Player Statements
Let's carefully examine the two given statements, focusing on the groups of football players, cricket players, and hockey players:
- Statement 1: Some football players play cricket.
- Statement 2: All cricket players play hockey.
To understand the logical flow, let's break down each statement individually:
- "Some football players play cricket": This statement signifies that there is an overlap between the group of football players and the group of cricket players. It means that at least one, and possibly many, individuals are members of both groups. It does not imply that all football players play cricket, nor does it mean that all cricket players play football.
- "All cricket players play hockey": This is a universal statement. It establishes a complete inclusion: every single person who plays cricket is also a hockey player. There are no exceptions within the group of cricket players regarding their participation in hockey.
Connecting Football and Hockey Players
Now, let's combine the information from both statements to find a logical connection between football players and hockey players. This process is a form of logical deduction, similar to a syllogism.
From Statement 1, we identify a specific subgroup of individuals: those who are both football players and cricket players. Let's imagine this subgroup for a moment.
From Statement 2, we know a crucial rule: every single cricket player also plays hockey. Since the subgroup we identified from Statement 1 (the football players who play cricket) consists of cricket players, they must, by definition of Statement 2, also be hockey players.
Therefore, the individuals who are both football players and cricket players are necessarily also hockey players. This means that there exists at least one individual who is a football player and also a hockey player.
We can represent this using set notation:
- Let be the set of football players.
- Let be the set of cricket players.
- Let be the set of hockey players.
Statement 1 implies: (The intersection of the set of football players and cricket players is not empty).
Statement 2 implies: (The set of cricket players is a subset of the set of hockey players).
If there is an element such that and (from Statement 1), and since all elements of are also in (from Statement 2), then that same element must also be in . Consequently, and , which means .
This directly leads to the logical conclusion: Some football players play hockey.
Evaluating the Options for Logical Conclusion
Let's examine each given option and determine whether it logically follows from the two original statements:
Based on our detailed analysis and logical deduction, the only statement that logically follows from the two given statements is that Some football players play hockey.

Evaluating the Options for Logical Conclusion
Let's examine each given option and determine whether it logically follows from the two original statements:
| Option | Analysis | Logically Follows? |
|---|---|---|
| Some football players play hockey. | This option aligns perfectly with our deduction. Since some football players are also cricket players, and all cricket players are hockey players, it must be true that those specific football players who play cricket also play hockey. | Yes |
| No football player plays hockey. | This statement directly contradicts our logical conclusion that some football players do play hockey. Therefore, it does not logically follow. | No |
| All hockey players play football. | We only know that all cricket players play hockey, and some football players play cricket. We have no information to support the claim that every single hockey player must also be a football player. There could be many hockey players who do not play cricket and consequently may not play football. | No |
| All football players play hockey. | The first statement specifies "some" football players play cricket, not all. Therefore, we cannot conclude anything about the hockey-playing habits of all football players, only about the subgroup who also play cricket. This statement is too broad and not supported by the given information. | No |
