The question at hand is: 'Which one is singular?' The correct answer is: hypothesis. <br>Below is a detailed explanation for why this is the correct choice and why the other options are not.

In the English language, nouns can exist in singular or plural form. Singular nouns refer to one unit of a thing, person, or concept, while plural nouns indicate more than one. The provided options demonstrate the complexity of pluralization, often derived from Latin or Greek origins.

1. agenda: Although commonly referred to as a singular noun in modern usage, 'agenda' is historically the plural form of the Latin 'agendum'. In classical contexts, 'agendum' (a single item to be done) is singular, while 'agenda' refers to multiple items. Therefore, 'agenda' is technically a plural noun.

2. foci: This is the plural form of 'focus'. In geometry and other fields, 'focus' refers to a single point of convergence, while 'foci' refers to multiple such points. Hence, 'foci' is plural.

3. syllabi: This is the plural form of 'syllabus'. 'Syllabus' refers to a singular outline or summary of a course. When referring to multiple such outlines, 'syllabi' is used. Therefore, 'syllabi' is plural.

4. hypothesis: 'Hypothesis' is a singular noun that refers to a proposed explanation for a phenomenon used as a basis for further investigation. The plural form of 'hypothesis' is 'hypotheses'. Therefore, in its original form 'hypothesis' is singular.

5. media: This is the plural form of 'medium'. When considering communication channels, 'medium' refers to a single method (e.g., television), whereas 'media' encompasses multiple methods (e.g., television, radio, newspapers). Thus, 'media' is plural.

Thus, 'hypothesis' is the correct answer since it is the only option that is singular in its basic form. Understanding these nuances is important for accurate communication, particularly in academic and scientific contexts.
