Rate the following argument fragment on its writing, argument, and language skills:
Evidence: As described in paragraph 6, a students facial expression has the power to change a lesson. If this is true, could a student not simply fake an emotion to get out of assignments or slack off by acting confused. The article claims that the software can pick up on fake smiles, but can it detect false expressions for other emotions as well? Another flaw within this system is the emotions the technology is capable of percieving, paragraph 6 disscusses the modification of a lesson based on boredom or confusion detected by the computer, however, neither of these two feelings are listed in the 6 emotions that the software is capable of detecting (paragraph 3). These two major flaws within the software lead to only one conclusion, the technology is simply not advanced enough to take on the role of a teacher.
