Yowza!  A ton of fun!   A picture of a 2,528 lb pumpkin that, as of now, is the heaviest pumpkin grown in the United States. 

6. a.  Percy Bysshe Shelley

7. b. Persephone (Virgo)
The Sun moved into the constellation Virgo on September 15th, heralding her return to the Plains of Asphodel, the abode of the dead governed by Hades. Hades abducted Virgo and brought her to the underworld, much to the distress of her mother, Demeter, goddess of the harvest.   Demeter was so distraught at her daughter's abduction, she neglected to preside over the fields, forests and crops.  The once verdant world withered and grew barren.  Fearing a global famine, Zeus intervened and persuaded Hades to accept a compromise by which Virgo would remain with her mother for half of the year, while living with Hades during the other half, spring/summer and autumn/winter, respectively.  Zeus would have preferred to have Virgo remain with Demeter all year.  However, soon after the abduction, Hades persuaded Virgo to eat pomegranates, the fruit of death.  As a result, Virgo was required to always return to the underworld each year.

8. b. mid October; purple
Foliage admirers might balk and insist that purple isn't prevalent.  However, according to foliage surveys, the state is empurpled by the royal shade in mid October as the leaves decay.

9. b. Virgo the Maiden
Of all the Zodiac constellations, the Sun spends the most time in Virgo.   The Sun appears to enter the Virgo region on September 15th and leaves on October 30th.  

10.  c. twice
It is certainly not common.
The autumnal equinox will occur on September 21st GMT in 2092 and 2096.
In all the other years this century, the autumnal equinox will occur on September 22 or September 23
