Answer

To answer the question regarding the scientific name "Rattus rattus," we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Scientific Names**: Scientific names are used to uniquely identify species and are composed of two parts: the genus name and the species name.

2. **Identifying the Components**: In the name "Rattus rattus":
- The first part, "Rattus," is the genus name.
- The second part, "rattus," is the species name.

3. **Defining Binomial Nomenclature**: The system of naming organisms using two names (genus and species) is called binomial nomenclature. This system was developed by Carl Linnaeus.

4. **Identifying Totonyms**: A totonym is a specific type of scientific name where the genus and species names are the same. In this case, "Rattus rattus" qualifies as a totonym because both the genus and species names are "Rattus."

5. **Evaluating the Options**: The options provided are:
- Binomial nomenclature
- Totonym
- Synonym
- Both 1 and 2

6. **Selecting the Correct Answer**: Since "Rattus rattus" is an example of both binomial nomenclature and a totonym, the correct answer is "both 1 and 2."

### Final Answer:
The scientific name "Rattus rattus" is an example of both binomial nomenclature and a totonym. Therefore, the correct answer is **both 1 and 2**.
