There was ___ in my suitcase so I could carry it without ___ effort ?

The sentence "There was ___ in my suitcase so I could carry it without ___ effort" requires words that make the context sensible and grammatically correct.

Option B, "nothing/any," is the correct choice. The phrase "There was nothing in my suitcase" suggests that the suitcase was empty, which logically explains why the speaker could carry it easilysince an empty suitcase requires little to no effort to lift or move.

On the other hand, the second part of the sentence, "without any effort," indicates the absence of effort required for carrying it. The word "any" is appropriate here because it suggests that regardless of how much effort one typically expects to exert, none was needed. In this context, "any" works well in negative constructions, reinforcing the idea of complete lack of effort.

The other options fail to convey the same clear meaning. For example, option A "something/no" implies the presence of items in the suitcase, either too vague or contrary to the context that suggests ease of carrying. Therefore, the combination of "nothing" and "any" effectively communicates the intended message of effortless carrying due to the suitcase being empty.
