Migrations

Emma has created the tournament database schema using the following models:

type Team struct { // Model of the `teams` table
    gorm.Model
    Name string
}

type Player struct { // Model of the `players` table
    gorm.Model
    FirstName string
    LastName  string
    Age       int
    TeamID    uint
}

type Game struct { // Model of the `games` table
    gorm.Model
    TeamID        uint
    HomeTeam      Team
    HomeTeamID    uint
    HomeTeamScore uint
    AwayTeam      Team
    AwayTeamID    uint
    AwayTeamScore uint
    Date          time.Time
}

Now Emma wants to run two single migrations using the db.Migrator() interface to propagate the following changes:

1. Change the name of the games table to matches;
2. Remove the age column in the players table.

Your task is to help Emma select from below the two (2) correct code lines required to achieve the objectives above.
