1. based on the text, what kinds of sicknesses can very high radiation exposure and long - term radiation exposure cause?
2. based on the text, how have people harnessed the power of radiation? use evidence from the text to support your answer.

Explanation:

The first sentence has a contrast between the harmful effects of high - radiation exposure (sickness or death) and its beneficial use for health. “Although” is a subordinating conjunction used to introduce a contrast. “However” is a conjunctive adverb and needs proper punctuation and sentence structure which is not applicable here. “Before” and “Because” do not convey the contrast. For questions 8 and 9, without the actual text, we can't answer them. But for the first part, we analyze the relationship between the two clauses in the sentence.

Answer:

A. Although
