Input: Article: Rome had a semi-divine ancestor in the Trojan refugee Aeneas, son of Venus, who was said to have established the nucleus of Roman religion when he brought the Palladium, Lares and Penates from Troy to Italy. These objects were believed in historical times to remain in the keeping of the Vestals, Rome's female priesthood. Aeneas had been given refuge by King Evander, a Greek exile from Arcadia, to whom were attributed other religious foundations: he established the Ara Maxima, "Greatest Altar," to Hercules at the site that would become the Forum Boarium, and he was the first to celebrate the Lupercalia, an archaic festival in February that was celebrated as late as the 5th century of the Christian era.

Now answer this question: Of what did Aeneas establish the central feature?

Output: Roman religion

Input: Article: This method involves coating LEDs of one color (mostly blue LEDs made of InGaN) with phosphors of different colors to form white light; the resultant LEDs are called phosphor-based or phosphor-converted white LEDs (pcLEDs). A fraction of the blue light undergoes the Stokes shift being transformed from shorter wavelengths to longer. Depending on the color of the original LED, phosphors of different colors can be employed. If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.

Now answer this question: In pcLEDs method, a fraction of what light is used?

Output:
blue
