You need MANY MANY more commas. Stop using “you” as well. Don’t use “you” “me” “I” etc. Fix your grammar first and foremost, you’re missing a comma in almost every sentence.

In paragraph 5, the author states, "subjects who were shown their engagement level while performing a task were able to learn to control their concentration and outperformed control groups while reporting a lower perceived workload." This detail shows the connection the author makes between feedback (showing users their engagement level) and performance (learning to control concentration and outperforming control groups).
The correct answer is C. The author uses a chronological structure to provide a timeline of events that led to the discovery of the technology.
Throughout the text, the author starts by discussing the technique of measuring brainwaves using smart glasses and then goes on to explain the history of neurofeedback. The author describes how a scientist at NASA's Langley Research Center invented a way to translate brainwave output to characterize attention levels in the 1990s. Then, they mention how the engagement index was used for pilot training and the subsequent development of the SMART BrainGames system.
Later in the text, it is explained how Domenic and Devon Greco exclusively licensed aspects of NASA's system and founded CyberLearning Technologies, which used video games to improve concentration. It is then mentioned how they came up with the idea of applying neurofeedback technology to smart glasses. The text continues with the establishment of Narbis by Devon after his father's death.
The author concludes with the current status and applications of the technology, including the use of smart glasses for studying and attention improvement, as well as the potential interest from professional athletes and clinics.
Thus, the text follows a chronological structure, providing a timeline of the events and developments related to the technology discussed.
The most effective research question based on the information in paragraphs 1-3 is:
A. How does NASA's use of neurofeedback compare to how it was used with pilots?
Justification: Paragraphs 1-3 provide background information on the development of neurofeedback and its application in pilot training at NASA's Langley Research Center. It explains how an engagement index was invented to measure attention levels and how pilots were trained to control their concentration. Therefore, the research question that focuses on the comparison of NASA's use of neurofeedback with its application in pilot training is the most relevant to the information presented in the given paragraphs.
The correct answer is: D. Both the passage and photographs feature the glasses, but only the photographs give credit to researcher Alan Pope.
This can be determined by analyzing both the passage and the photographs provided. In the passage, it is mentioned that "A new pair of smart glasses uses a technique invented at NASA." However, there is no specific mention of who invented the technique or the glasses. On the other hand, in the photographs, there is a caption that specifically credits Langley Research Center engineer Alan Pope for building and patenting the biofeedback training devices that eventually led to the creation of the attention-training glasses.
Therefore, the photographs provide additional information that is not mentioned in the passage, specifically giving credit to Alan Pope as the inventor of the glasses.
The correct answer is C. The sentence from paragraph 11 explains how the glasses allow users to apply the system to real life and engage in activities of their choice. This statement supports the central idea of the text that the glasses are meant to be used in everyday situations. It emphasizes that the technology has been made accessible for practical and personal use.
