Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: After the death of his older half-brother and financial support, Carl Erik, when Lars Levi was only a teenager, Laestadius mourned the deaths of his mother in 1824, his dad in 1832, and his younger brother Petrus in 1841. At least two of Laestadius's own sons predeceased him as well . Around 1833 Laestadius suffered from an ailment which the doctors first thought was pneumonia. He recovered. In the 1840s, Laestadius suffered from severe typhoid fever and later tuberculosis. Towards the end of his life, Laestadius experienced "impending blindness" and contracted a cholera-like illness.
Student:
How many ailments total did Laestadius suffer from?
