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: Three star systems appear to have exoplanet. HD 9446 is a sun-like star around 171 light-years distant that has two planets of masses 0.7 and 1.8 times that of Jupiter, with orbital periods of 30 and 193 days respectively. WASP-56 is a sun-like star of spectral type G6 and apparent magnitude 11.48 with a planet 0.6 the mass of Jupiter that has a period of 4.6 days. HD 13189 is an orange giant of spectral type K2II about 2-7 times as massive as the sun with a planetary or brown dwarf companion between 8 and 20 times as massive as Jupiter, which takes 472 days to complete an orbit. It is one of the largest stars discovered to have a planetary companion.

A: How many of HD 9446's planetary companions are larger than Jupiter?

Q: Passage: Lithuanian GDP experienced very high real growth rates for decade up to 2009, peaking at 11.1% in 2007. As a result, the country was often termed as a Baltic Tiger. However, 2009, due to Financial crisis of 2007–2008 marked experienced a drastic decline – GDP contracted by 14.9% and unemployment rate reached 17.8% in 2010. After the decline of 2009, Lithuanian annual economic growth has been much slower compared to pre-2009 years. According to IMF, financial conditions are conducive to growth and financial soundness indicators remain strong. The public debt ratio in 2016 fell to 40 percent of GDP, to compare with 42.7 in 2015 (before global finance crisis – 15 percent of GDP in 2008).

A:
How many percent of GDP did the public debt ratio change from 2015 to 2016?
