Question 43 says according to the passage, 2 exposure to light allows seeds to what? 3 So since this question starts off with saying according to the passage, 4 we know the answer is going to come directly from text evidence. 5 So let's go back into the passage and see where we can find that 6 if we look in this third paragraph here, 7 it starts off by saying they start up the soil in one sample of 8 each pair in the light and start up the other sample of each pair 9 of in the dark.
