### Determine the Major Product of the Following Reaction

In this problem, you are tasked with determining the major product of a given chemical reaction. The reactant consists of a cyclopentyl group attached to a triple bond (alkyne). The reaction conditions include the presence of sodium (Na) and liquid ammonia (NH₃).

#### Reaction Details:
- **Reactant:** Cyclopentyl group attached to an alkyne.
- **Reagents:** Sodium (Na) and liquid ammonia (NH₃).

Given these conditions, the reaction is likely a reduction of the alkyne to a trans-alkene. This type of reaction is known as the Birch reduction. The alkyne will be converted to a trans-alkene rather than a cis-alkene due to the nature of the reaction mechanism under these conditions.

#### Expected Major Product:
The major product will exhibit a trans-configuration where the carbon atoms previously involved in the triple bond now form a double bond, and each of these carbon atoms will have a hydrogen atom added (reduction).

The structure can be depicted as follows:
- **Reactant:** Cyclopentyl-ethyne.
- **Major Product:** Trans-cyclopentyl-ethene.

This product alignment influences the final molecular geometry and properties of the compound significantly, often stabilizing the structure further compared to other potential isomeric products.
