The most difficult the Philip­pines riddles

The Banaue Rice Terraces were carved into the mountains of Ifugao in the Philippines by ancestors of the indigenous people. It is commonly thought that the terraces were built over 2,000 years ago with minimal equipment, largely by hand. They are frequently called the "Eighth Wonder of the World".

Mount Apo is the largest and the tallest solfataric mountain on the island of Mindanao and in all of the Philippines. The mountain has an elevation of 9,692. Six indigenous groups of people including Bagobo, Ubos, and Tagacaol live around the regions of Mount Apo and consider the mountain a sacred place and also a place for worship rituals.

With over 50 % of the country's total population, it is also the most populous island in the Philippines and the fourth most populous in the world (after Java, Honshu, and Great Britain).

This slightly-larger-than-A4 sized banknote printed by the Philippine government in 1998 is claimed to be the largest piece of paper money in the world. It marked 100 years of Philippine independence from Spanish rule and was only offered to collectors, as if tacitly admitting to its own impracticality.

The Bataan Death March began in Mariveles on Bataan in the Philippines and the Filipino and American prisoners continued with little food or water for days beginning on April 9th. The march took place over a stretch of 60 miles and ended at Capas. The sick and injured were mistreated and died along the route. The Bataan Death March was just one of the brutal acts conducted by Japan during World War II.

After World War II, Lubang Island was where Hiroo Onoda, a Japanese army intelligence officer, hid in the jungles when the Allies reclaimed the Philippines. Despite flyers being dropped by airplanes in his hiding area, he adamantly believed that the war was not over yet. In March 1974, he was officially relieved of duty, 29 years after the end of the war, making him one of the last Japanese soldiers to surrender.
