this question did not make sense to me and I would appreciate some suggestions

Can you give me some suggestions on this question

Detail.cshtml 
@model Treehouse.Models.VideoGame

@{
    ViewBag.PageTitle = "Video Game Detail";
}

<h1>@Model.Title</h1>

<h5>Favorite: @Model.Favorite</h5>

<h5>Description:</h5>
<div>@Model.Description</div>

<h5>Characters:</h5>
<div>
    <ul>
        @foreach (var character in Model.Characters)
        {
            <li>@character</li>
        }
    </ul>
</div>
VideoGame.cs 
namespace Treehouse.Models
{
    // Don't make any changes to this class!
    public class VideoGame
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public string[] Characters { get; set; }
        public string Publisher { get; set; }
        public bool Favorite { get; set; }

        public string DisplayText
        {
            get
            {
                return Title + " (" + Publisher + ")";
            }
        }
    }
}

It's asking you to run a ternary check on the Favorite property, which is a Boolean, then set the Label "Property: " in the view to say "Yes" in case of true, and "No" in case of false, so it will be something like this:

   <h5>Favorite: @(Model.Favorite ? "Yes" : "No")</h5>

A ternary operation is basically a simplified IF check that runs on a single line, so the check in this case is Model.favorite, since it's a boolean it can either be true of false, the "?" is what tells the interpreter/compiler that this is a ternary check, then whatever comes right after the "?" is what will happen in case that checks pass as true, the ":" is the same thing as an ELSE in a IF, so whatever comes after it is what will happen if the check pass as false.

I guess not everyone shares your opinion about the quality of the answers. :stuck_out_tongue_winking_eye:

You're asked to change true or false into "Yes" or "No".

The challenge says to do this with the ternary operator. Do you remember what that is? It uses a question mark and a colon, like this:

/*value or expression to test*/ ? /*value to return if true*/ : /*value to return if false*/

So, to begin with Model.Favorite is either true or false. Your task is to apply a ternary expression to use it to get either the string "Yes" or "No".
