This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Q: Passage: The French continued to pressure Siam, and in 1906-1907 they manufactured another crisis. This time Siam had to concede French control of territory on the west bank of the Mekong opposite Luang Prabang and around Champasak in southern Laos, as well as western Cambodia. France also occupied the western part of Chantaburi. In the Franco-Siamese Convention of 13 February 1904, in order to get back Chantaburi, Siam had to cede Trat to French Indochina. Trat became part of Thailand again on 23 March 1907 in exchange for areas east of the Mekong river including Battambang, Siam Nakhon, and Sisophon. The British interceded to prevent more French expansion against Siam, but their price, in 1909 was the acceptance of British sovereignty over Kedah, Kelantan, Perlis and Terengganu, under the Anglo-Siamese Treaty of 1909. All of these ceded territories were on the fringes of the Siamese sphere of influence and had never been securely under Siamese control, but being compelled to abandon all claim to them was a substantial humiliation to both king and country. In the early 20th century these crises were adopted by the increasingly nationalist government as symbols of the need for the country to assert itself against the West and its neighbours.
A:
Aside from the territory on the west bank of the Mekong, the Siam had to concede French control of which other territories?
