Questions & Answers about Strategie a náhoda jsou důležité.
Here, strategie is most naturally singular: strategy.
This is a very common point of confusion because strategie has the same form in:
- nominative singular
- nominative plural
So by itself, strategie can mean either strategy or strategies depending on context.
In this sentence, the intended reading is singular because it is paired with another singular noun, náhoda (chance/coincidence), and together they form a compound subject:
- strategie a náhoda = strategy and chance
Even though each noun is singular, the combination is plural in meaning, so the verb is plural.
