To determine the correct similarity between the passages, additional context about the actual content of the passages would be necessary. However, based on the provided options, choice A and B both relate to potential harm and negative health effects of cell phones, making them relevant if the passages discuss those themes. Choice C and D suggest a focus on social relationships and parental involvement, which would depend on the content of the passages as well.
If the passages indeed discuss cell phones and their health effects, the answers would likely be A or B. If they focus on social dynamics or parental involvement, then answers C or D would be more appropriate. Without more specific information about the content of the passages, it is challenging to choose an option definitively.
If I had to choose based solely on the options, I would suggest:
B - Both passages show the negative health effects of cell phones.
This option reflects a common concern addressed in many discussions about technology and health.
