Singular to translate Plural?

Question

Why is “looking for solutions for their diseases” translated in the singular “su enfermedad” instead of the plural “sus enfermedades”? Thank you.

Hola Samantha S.
Great question! In Spanish, both "su enfermedad" (singular) and "sus enfermedades" (plural) can be used when referring to multiple people with their respective diseases. The singular form is often used in a more collective sense, grouping the idea of 'disease' rather than emphasizing individual conditions.
In this exercise, we have specifically instructed the use of the singular form in the hint. This helps reinforce a common Spanish usage where singular nouns are sometimes preferred in cases like this.
Hope this helps! Let us know if you have any other questions.
