It's asking you to initialize showFactButton just like the factLabel TextView. The Button has an ID "showFactButton" in xml as well.

Button showFactButton = (Button) findViewById(R.id.showFactButton);

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class FunFactsActivity extends Activity {
   private Button showFactButton;
  private TextView factLabel;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fun_facts);

        // Declare our View variables and assign them the Views from the layout file
        TextView factLabel = (TextView) findViewById(R.id.factTextView);
        Button showFactButton = (Button) findViewById(R.id.showFactButton);
    }
}
