In the following question on game classification, four games are listed (Baseball, Football, Hockey and Snooker). Three are outdoor field games played on a ground, while one is an indoor cue sport played on a table. Select the odd word from the given alternatives.

Introduction / Context:
This classification question focuses on differentiating between outdoor field sports and an indoor cue sport. The games listed are Baseball, Football, Hockey and Snooker. In three of these, teams play on a large outdoor ground or field, often involving running and tackling. One game is played indoors on a table using a cue and balls. Identifying this difference in playing environment and equipment will lead you to the odd one out.

Given Data / Assumptions:

• Baseball: outdoor team game played on a diamond shaped field with bat and ball.
• Football: outdoor team sport played on a rectangular ground with a ball.
• Hockey: typically an outdoor field sport (in field hockey) played with sticks and a ball on a turf or grass ground.
• Snooker: indoor cue sport played on a baize covered table using a cue and coloured balls.
• We classify games as outdoor field sports versus indoor tabletop or cue sports.

Concept / Approach:
The concept is to group games based on the type of playing area and style. Baseball, Football and Hockey are all field based sports that require large outdoor grounds, many players and vigorous physical movement. Snooker, in contrast, is played indoors on a special table and focuses more on precision and cue control than running or physical contact. This clear difference in environment and gameplay makes Snooker the odd one out among the four options.

Step-by-Step Solution:
Step 1: Consider Baseball.Baseball is played outdoors on a field. It involves running between bases and fielding across a large area.Step 2: Consider Football.Football is also played outdoors on a large rectangular ground, with two teams trying to score goals.Step 3: Consider Hockey.In its common field form, Hockey is played outdoors on grass or artificial turf with sticks and a ball. It is again a field sport.Step 4: Consider Snooker.Snooker is played indoors on a special table. Players stand around the table and strike balls with a cue stick; there is no large field or outdoor setting.Step 5: Identify the odd game.Because Baseball, Football and Hockey are outdoor field games, and Snooker is an indoor cue sport, Snooker is the odd one out.

Verification / Alternative check:
To verify, imagine where each game is played in a typical sports complex. Baseball, Football and Hockey occupy big outdoor grounds or stadiums, while Snooker is found in indoor halls or clubs on tables. They also differ in the number of players: the field games require large teams, whereas snooker is often played one versus one or in small groups. These practical differences in setting and structure confirm that Snooker is categorically different from the other three.

Why Other Options Are Wrong:
Baseball: Outdoor field sport, belongs to the main category.
Football: Another outdoor field sport, consistent with Baseball and Hockey.
Hockey: Field game played outdoors, so it is not the odd one.

Common Pitfalls:
Some may think of ice hockey as an indoor game, but the more typical exam reference is field hockey, which is outdoor. Even if one considers ice hockey, it is still played in a large arena, not on a small table. The intended distinction is clearly between large field or arena sports and the confined, table based cue sport of Snooker. Keeping this broader context in mind avoids misclassification.

Final Answer:
The odd word is Snooker, because Baseball, Football and Hockey are outdoor field games, whereas Snooker is an indoor cue sport played on a table.
