Answer: Thought is the process of thinking, while although includes explanations.
Explanation:
While though isn't always incorrect, it should be used to simply denote that something is contradictory to what you previously said. "I eat meat but I don't like vegetables." Though should not be used when you are giving an explanation for why something happened or what someone's opinion might be.
When voicing your opinion on a matter, use 'though'. Likewise, if you're explaining one of many possible outcomes of a situation then use 'though' as well. In these cases thought is required because there needs to exist a logical flow from one part of the sentence to another in order for everything to make sense and come together coherently without any contradictions being made between yourself
