Final answer:
When a person is bilingual and only one language is being used, both languages can remain active to some extent based on factors such as context and language proficiency.
Step-by-step explanation:
When a person is bilingual and only one language is being used, both languages can remain active. The level of activation for each language may vary depending on factors such as the context, language proficiency, and frequency of use.
For example, if a person is fluent in both English and Spanish and is primarily speaking English, their Spanish language skills can remain active to some extent. This means they can still understand and produce Spanish, although they may not be as proficient as when they are actively using it.
The level of activation for each language can be influenced by factors such as language exposure, language dominance, and individual language preferences. Some bilingual individuals may find it easier to switch between languages, while others may need more time to mentally shift from one language to another.
