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.

In Scotland, spending on trunk roads went up from £6.8 million in 1963/64 to £15.5 million in 1966/67, while in Wales, spending on Welsh roads went up from £21.2 million in 1963/64 to £31.4 million in 1966/67.

Question: Passage: The Bolshevik forces reached the Lithuanian territory on July 7, 1920, and continued to push the Polish troops. The Lithuanian Army moved to secure territories abandoned by the retreating Polish forces. They took Turmantas on July 7, Tauragnai and Alanta on July 9, Širvintos and Musninkai on July 10, Kernavė, Molėtai, and Giedraičiai on July 11, Maišiagala and Pabradė on July 13. On July 13 the Polish command decided to transfer Vilnius to the Lithuanians in accordance with the resolution of the Spa Conference. Lithuanians moved in, but their trains were stopped by Polish soldiers near Kazimieriškės. This delay meant that the Bolsheviks were the first to enter Vilnius on July 14. By the time first Lithuanian troops entered the city on July 15, it was already secured by the Soviets. Poland sought to have Russians in the city as it would create much less complications when Polish Army counterattacked. Despite the Peace Treaty, the Soviets did not intend to transfer the city to the Lithuanians. Indeed, there were indications that the Soviets planned a coup against the Lithuanian government in hopes to re-establish the Lithuanian SSR. Despite the setback in Vilnius, the Lithuanians continued to secure territories in the Suwałki Region. They took Druskininkai on July 17, Vištytis, Punsk, Giby, and Sejny on July 19, Suwałki on July 29, Augustów on August 8. The Polish units, afraid of being surrounded and cut off from the main Polish forces, retreated towards Łomża. The Lithuanian authorities started to organize themselves in the regained areas.

Answer: From July 7 to July 13 how many terriotories did the Lituanian Army take?
