Problem: In four months, Aonuma's team managed to present realistic horseback riding,[l] which Nintendo later revealed to the public with a trailer at Electronic Entertainment Expo 2004. The game was scheduled to be released the next year, and was no longer a follow-up to The Wind Waker; a true sequel to it was released for the Nintendo DS in 2007, in the form of Phantom Hourglass. Miyamoto explained in interviews that the graphical style was chosen to satisfy demand, and that it better fit the theme of an older incarnation of Link. The game runs on a modified The Wind Waker engine.
How long did it take to implement riding horses in a believable manner?

Since before 2000 BC, humans have utilized pesticides to protect their crops. The first known pesticide was elemental sulfur dusting used in ancient Sumer about 4,500 years ago in ancient Mesopotamia. The Rig Veda, which is about 4,000 years old, mentions the use of poisonous plants for pest control. By the 15th century, toxic chemicals such as arsenic, mercury, and lead were being applied to crops to kill pests. In the 17th century, nicotine sulfate was extracted from tobacco leaves for use as an insecticide. The 19th century saw the introduction of two more natural pesticides, pyrethrum, which is derived from chrysanthemums, and rotenone, which is derived from the roots of tropical vegetables. Until the 1950s, arsenic-based pesticides were dominant. Paul Muller discovered that DDT was a very effective insecticide. Organochlorines such as DDT were dominant, but they were replaced in the U.S. by organophosphates and carbamates by 1975. Since then, pyrethrin compounds have become the dominant insecticide. Herbicides became common in the 1960s, led by "triazine and other nitrogen-based compounds, carboxylic acids such as 2,4-dichlorophenoxyacetic acid, and glyphosate".
What is the earliest records of humans using pesticides?
A: before 2000 BC

Context and question: There are many Hokkien speakers among overseas Chinese in Southeast Asia as well as in the United States.

Many of the Hokkien dialects of this region are highly similar to Taiwanese and Amoy. Hokkien is reportedly the native language of up to 98.5% of the Chinese Filipino in the Philippines, among which is known locally as Lan-nang or Lan-lang-oe ("Our people's language"). Hokkien speakers form the largest group of Chinese in Singapore, Malaysia and Indonesia.[citation needed]
