"Tienes un hermano y una hermana, mayor y menor que tú, respectivamente."
Translation:You have a brother and a sister, older and younger than you, respectively.
That's a good point, but it sounded way different on the slow track yesterday- more like hira or hila rather than una. It definitely sounds like una in the playback provided above, but there's no slow version and I can't get back to one from here. It wasn't an important point anyway. Just a side comment with a little frustration mixed in.
