Final answer:
Abstract nouns like 'beauty,' 'success,' 'strength,' and 'indecision' can be used to fill in the blanks, reflecting qualities or concepts that are not physical but are integral to the sentences provided.
Step-by-step explanation:
The fill-in-the-blank spaces should be completed with suitable abstract nouns that describe non-physical qualities or ideas. For the sentence 'The girl was envied for her _,' an appropriate abstract noun could be 'beauty' or 'success,' which are qualities that can inspire envy. In the phrase 'The Spiderman for had to use great _ to lift the stone,' a fitting abstract noun is 'strength,' which signifies the physical power needed to lift heavy objects. Finally, the sentence '_ is what everyone decision', seems to be missing context, but 'decision' itself is an abstract noun referring to the conclusion reached after consideration. From the context provided, especially in the phrase 'No amount of thought, that night, could decide how many wished-for treasures the ten dollars, so lightly spoken of, would buy,' it appears that 'indecision' may be the abstract noun that completes the sentence, indicating a state of hesitancy or inability to make a decisive choice.
