this study looks at the relationship between screen time and depression and suicide rates in 506,820 adolescents in the u.s. between 2010 and 2015. (2) the data on screen time use and mental health issues came from two nationally representative surveys of students in grades 8 through 12. (3) suicide rates were calculated from national statistics collected by the centers for disease control and prevention fatal injury reports. (4) the analysis finds a clear pattern linking screen activities with higher levels of depressive symptoms/suicide - related ideation - that is, thinking about suicide - and suicidal attempts and nonscreen activities with lower levels. (5) among participants who used devices for over five hours each day, nearly half - 48% - reported at least one suicide - related outcome. in comparison, 29% of those who used devices for just an hour per day had at least one suicide - related outcome. (6) overall, during the time studied, suicide rates, depressive symptoms and suicide - related outcomes increased. what change, if any, needs to be made in sentence 1? a change between to of b insert a comma after depression c change adolescents to adolescants d no change needs to be made in sentence 1. what change should be made in sentence 3? a change prevention to preventions b insert a comma after statistics c change were to was d change injury reports to injury reports short answer: what is another way the author could transition into sentence 6?

Explanation:

1. In sentence 1, the phrase "screen time and depression and suicide rates in adolescents" is a bit of a run - on. It should be separated for clarity. Inserting a comma after "depression" makes it easier to read and understand the relationship being studied.
2. In sentence 3, "Suicide rates were calculated from national statistics collected by the Centers for Disease Control and Prevention" is a correct construction. No change is needed.
3. In sentence 4, "The analysis finds a 'clear pattern linking screen activities with higher levels of depressive symptoms/suicide - related ideation - that is, thinking about suicide - and attempts' is a complex sentence. No change is needed as it is grammatically correct and clearly conveys the analysis result.
4. For the transition into sentence 6, a more effective transition could be "Moreover," to show an additional related point about the overall findings of the study.

Answer:

1. B. Insert a comma after depression
2. D. No change needs to be made
3. D. No change needs to be made
4. A more effective transition could be "Moreover,"
