"In Praise of Slacking," lacks objective textual evidence, which undermines textual structure.
This is because, in an argumentative text, the structure must present an argument, that is, the author's opinions, followed by textual evidence.
A counter-argument contexts the author's argument, showing that this argument is incorrect.
In that case, to create a  counter-argument, you must:
- Read the author's argument and understand the main idea of that argument.
- Present a counter-argument and present textual evidence that reinforces and shows that the counter-argument is correct.
- This evidence can be data, graphs, examples, and any kind of real information that can confirm the counter-argument.
If the argument has enough textual evidence to confirm it, it means that it is convincing, otherwise, it is unconvincing.
