Teacher:We would like you to assess the QUALITY of each of the following argument (discussing Gay Marriage) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of gay marriage. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gay marriage.
Teacher: Now, understand the problem? Solve this instance: The main point being made is thus: Altruistic behaviour by a unit of evolution that hunders itself towards units of evolution that also actually hinder their own reproductive potential would be extremely unlikely to saturate the gene pool.
Student:
Invalid
