Final answer:
The phrase 'Conviene que...' typically uses the subjunctive mood to express suggestions or requirements, not factual statements.
Step-by-step explanation:
When you encounter the phrase Conviene que..., you are generally dealing with the subjunctive mood. This mood is used to express various scenarios including wishes, suggestions, or requirements, and it is also commonly used to state hypothetical situations or events that are unlikely. In contrast to the indicative mood, which states facts, opinions, or questions, the subjunctive is more about expressing subjectivity and uncertainty.
For example: Conviene que estudies para el examen (It is advisable that you study for the exam). Here, the verb estudies is in the subjunctive mood, reflecting that this is a suggestion or a desirable action rather than a statement of fact. Furthermore, the subjunctive mood often follows certain conjunctions that reflect conditions such as although, because, and expressions of necessity, possibility, or doubt.
