Given the task definition and input, reply with output. 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: The Packers fell behind Detroit 14-0, but regained momentum when defensive lineman Mike Daniels returned a Lions fumble 43 yards for a touchdown, helping to put the Packers down only 14-10 at halftime. On their opening drive of the second half, Aaron Rodgers gave the Packers the lead for the first time with a 27-yard touchdown run. The Lions would tie the game 17-17 on a Jason Hanson field goal, and after both the Packers and the Lions would both miss field goals, the Packers finally got the lead for good on a 14-yard touchdown run by rookie DuJuan Harris. A Mason Crosby field goal gave the Packers a sure 27-17 lead with just over 4 minutes left in the game. The Lions would kick a field goal with 7 seconds left, but failed the onside kick attempt, giving the Packers a 27-20 win and eliminating the Lions from playoff contention. With a win against the rival Bears the following week, the Packers can clinch the NFC North division.
How many points did Green Bay trail by at the half?
