- Conjugation is a kind of bacterial reproduction
- Paramecia will conjugate to increase genetic variation under harsh environment
- Hence, a paramecium can conjugate

- Amoebas reproduce asexually through fission
- Conjugation is a kind of bacterial reproduction
- Hence, an amoeba cannot conjugate

- A paramecium can conjugate
- An amoeba cannot conjugate
- Therefore, a paramecium can conjugate but an amoeba cannot conjugate

Therefore, a paramecium can conjugate but an amoeba cannot conjugate
Question: Which is true about reproduction for both an amoeba and a paramecium?
Context: - Amoebas reproduce asexually through fission 
- Conjugation is a kind of bacterial reproduction 
- Paramecia will conjugate to increase genetic variation under harsh environment
