TASK DEFINITION: Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.
PROBLEM: 'The worst student' is the student who is bad at things. In this case, 'worst' simply describes the noun. Following this logic, your 'worst enemy' would be the person who is very bad at being your enemy, thus is actually your best friend. Your 'worst enemy' is actually the enemy who is very good at being your enemy. Thus, in this context, 'worst' acts to amplify the inherent negative intent of the noun. 'Worst disaster' would be another example of this. Is this just a matter of context or there some science behind the interprettation of a negative adjective applied to a negative noun?.

SOLUTION: Don't confuse English language with the mathematical theory. The adjective worst qualifies the noun enemy with even more bad values. So, a worst enemy is more dangerous than a normal enemy.

PROBLEM: As in 'the timeslot given to completing the task'. Would also be interested to hear if there's different usages for different scenarios.

SOLUTION: According to dictionary.com, it should be two separate words 'time slot'. This useful article on compound words offers the following advice: Many of them are found in the dictionary and are not subject to our interpretation, our judgment, or our whim. Start with your dictionary before applying any other guidelines. I would be inclined to follow that advice, and use the dictionary version: time slot.

PROBLEM: What's a word that means 'not knowing everything'? This would serve as a complementary antonym of omniscient, which means having infinite knowledge, or simply 'all-knowing'. Thesaurus.com shows these possible words: stupid (opposite of being clever, which = being omniscient) unknowing (opposite of being knowing, which = being omniscient) fallible (opposite of being infallible, which means 'not able to make mistakes', which = being omniscient, since I can know everything and still make mistakes) erring (which means 'capable of making mistakes', which = being omniscient, since I can know everything and still make mistakes) imperfect (opposite of being perfect, which is a superset of being omniscient... how could I be perfect if I'm both omniscient and fallible?) faulty (which means 'to have fault(s) / defect(s)', is the opposite of 'to have no fault(s) / defect(s)', which means being perfect, which = being omniscient) ignorant (which means 'having inadequate knowledge', is the opposite of 'having adequate knowledge', which = having infinite knowledge) uneducated (opposite of being educated, which = being omniscient) unaware (opposite of being aware, which = being omniscient) uninformed (opposite of being informed, which = being omniscient) Yet, none of them are true antonyms for omniscient. Is there an alternative?.

SOLUTION:
According to reference.com, the Random House dictionary registers unomniscient as a legitimate word. There are a handful of hits on Google Books which include the following examples: Chaucer deepens Jean de Meun's joke about the God's ersatz divinity: immediately after the God has just issued some clearly unomniscient judgments ... If at every world, God knows at that world only the propositions whose truth-values are modally constant, then it would seem that God is necessarily unomniscient. There are actually two types of unomniscient focus, since the narrator may know the same as or even less than the characters. The impossibility of an unomniscient intelligence demonstrating the supposed contradiction, and thus transforming our universe into an untrustworthy universe, with which one can have no intercourse, is the attitude primarily assumed towards ... Also of interest is the term bounded rationality: Bounded rationality is the idea that in decision-making, rationality of individuals is limited by the information they have, the cognitive limitations of their minds, and the finite amount of time they have to make a decision.
