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.

Passage: Not even their Week 3 Bye could help out Oakland. Despite jumping out to a 21-3 lead and going into halftime ahead 21-10, and despite a touchdown by linebacker Sam Williams and two interceptions by cornerback Nnamdi Asomugha, the Raiders failed to shut down the Browns' offense, allowing 14 third quarter points. In the days after the game, coach Art Shell said that Raider higher-ups responsible for deciding whether or not a challenge is worthwhile told him that one was not following a third and 16 play from the Cleveland Browns' 45-yard-line that went for fifteen yards in the fourth quarter. Shell said that after reviewing the telecast of the game, "I was miffed, because we should have challenged it." Following that, a fourth and 1 hand-off to LaMont Jordan was stopped in the backfield for a loss of two, resulting in a turnover on downs.
How many more points did Oakland have at halftime relative to the Browns?
