I don't think they are saying you should remove the checks, it's only about these lines of code:
```php
$resource = $this->resolver->resolve($absoluteName, $renderer);
return $resource;
```
There is no need for the introduction of the new variable `$resource`, a return statement is enough:
```php
return $this->resolver->resolve($absoluteName, $renderer);
```
So simply replace those 2 lines of code with this 1 line of code :wink:
