Learn Spanish (Latin America): El experto presentó el análisis al tribunal. - The expert presented the analysis to the court.

It is singular here, which you can tell by the singular article el. Words ending in -sis (like análisis, crisis, or hipótesis) are invariable, meaning they don't change spelling in the plural. To talk about multiple analyses, you only change the article: los análisis.

Why translate "court" as tribunal instead of corte?

While both mean "court," tribunal is the most standard word in Latin America for a regular court of justice or a panel of judges handling a case. Corte is typically reserved for higher-level judicial bodies, like the Supreme Court (la Corte Suprema), or a royal court.

How would I connect this sentence to a logical result using this lesson's grammar, like "consequently, they won the case"?

You can append a formal illative connector like en consecuencia or por lo tanto, followed by a verb in the indicative mood. For example: El experto presentó el análisis al tribunal; en consecuencia, ganaron el caso. (The expert presented the analysis to the court; consequently, they won the case).

Why use the preterite presentó rather than the imperfect presentaba?
