Note:
* target 2:
GetType() is a method you call on individual objects, to get the execution-time type of the object.
Incorrect: typeof is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.

You have the following code:
You need to display all of the vehicles that start with the letter "A".
How should you complete the code? To answer, drag the appropriate code elements to the correct targets. Each code element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Note:
Target 1:
The role of IComparable is to provide a method of comparing two objects of a particular type. This is necessary if you want to provide any ordering capability for your object.
Incorrect: The role of IComparer is to provide additional comparison mechanisms. For example, you may want to provide ordering of your class on several fields or properties, ascending and descending order on the same field, or both.
Target 2, Target 3:
Example:
// Implement IComparable CompareTo method - provide default sort order.
int IComparable.CompareTo(object obj)
{
car c=(car)obj;
return String.Compare(this.make,c.make);
}

You are implementing a new method named ProcessData. The ProcessData() method calls a third-party component that performs a long-running operation to retrieve stock information from a web service.
The third party component uses the IAsyncRcsult pattern to signal completion of the long-running operation so that the UI can be updated with the new values.
You need to ensure that the calling code handles the long-running operation as a 5ystem.Threading_Tasks.Task object to avoid blocking the Ul thread.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
