Although it looks peaceful enough in a glass, an explosive exothermic reaction forms water from hydrogen and oxygen, two of the most common elements in the universe, come in contact in an unattached molecular state.
A. an explosive exothermic reaction forms water from
B. an exothermic reaction explosively forms water when
C. when water is formed in an explosive exothermic reaction,
D. water is explosively formed in an exothermic reaction from
E. water is formed in an explosive exothermic reaction when
The structure of the sentence is --->Depended Clause, Independent clauseIntended Meaning: Although wather looks peaceful in glass, it is formed in a some reaction. This reaction happens when Hydrogen and Oxygen come is mixed with some molecular thing.
Errors in the given sentence:
1. As the sentence starts with 'Although it', it should follow the proximity rule and should be next to the modifier, which is intended to modify. It doesn't make sense to say that the Reaction looks peaceful, it is water, which looks peaceful.
2. As per the intended meaning, Water is not created from Hydrogen and Oxygen, Water is created when these two chemicals are mixed with something. So, Using 'From' doesn't make any sense.
Answer choice Analysis:A. an explosive exothermic reaction forms water from
-- Wrong for the two reasons mentioned aboveB. an exothermic reaction explosively forms water when
-- it corrects the 'From' Error mentioned above , but modification error still existsC. when water is formed in an explosive exothermic reaction,
-- Now, this changes the meaning and sequences of the original sentence. Moreover, the 'Although it...Modifier' have no proper entityD. water is explosively formed in an exothermic reaction from
-- Modifier issue fixed; use of preposition 'From' changes the meaning; the word 'explosively' is modifying 'Formation' of water, but in the original sentence, Explosively is intended to modify the 'Exothermic reaction' E. water is formed in an explosive exothermic reaction when
-- Correct choice Hope that Helps
