Hi Zubeyr

We first need to create a new Call object giving it a useful variable name (I used call), for example:

Call call...

We then need to set it using the OkHttpClient method newCall(). An OkHttpClient object has already been created called client so we'll update that line of code as follows:

Call call = client.newCall()

And lastly the task asks us to pass in a parameter of Request type. Again a Request object has already been created called request so we'll drop that into the newCall() method as below:

Call call = client.newCall(request);

Hope it helps!
