instruction:
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 Indice de Precios y Cotizaciones (IPC, the general equities index) is the benchmark stock index on the Bolsa. In 2005 the IPC surged 37.8%, to 17,802.71 from 12,917.88, backed by a stronger Mexican economy and lower interest rates. It continued its steep rise through the beginning of 2006, reaching 19,272.63 points at end-March 2006. The stockmarket also posted a record low vacancy rate, according to the central bank. Local stockmarket capitalisation totalled US$236bn at end-2005, up from US$170 bn at end-2004. As of March 2006 there were 135 listed companies, down from 153 a year earlier. Only a handful of the listed companies are foreign. Most are from Mexico City or Monterrey; companies from these two cities compose 67% of the total listed companies.

Passage: Trying to snap a two-game losing streak, the Cowboys went home for a Week 7 NFC East duel with the New York Giants on Monday night.  Dallas got the opening strike in the first quarter as quarterback Tony Romo found tight end Jason Witten on a 4-yard touchdown run, followed by a 26-yard field goal from kicker David Buehler.  The Giants answered with quarterback Eli Manning completing a 7-yard touchdown pass to wide receiver Hakeem Nicks.  The Cowboys would add onto their lead in the second quarter as Buehler booted a 41-yard field goal, followed by rookie wide receiver Dez Bryant returning a punt 93 yards for a touchdown.  New York took the lead with Manning throwing an 8-yard touchdown pass to Nicks and a 14-yard touchdown pass to wide receiver Steve Smith.  Afterwards, the Giants closed out the half with kicker Lawrence Tynes getting a 53-yard field goal. During the half, Dallas quarterback Tony Romo was suffered a broken left clavicle on a completion from a blocking error. Dallas' deficit increased in the third quarter as Manning completed a 25-yard touchdown pass to wide receiver Mario Manningham, followed by running back Brandon Jacobs getting a 30-yard touchdown run.  The Cowboys began to rally in the fourth quarter as quarterback Jon Kitna found Bryant on a 15-yard touchdown pass (with a successful two-point conversion pass to Witten), yet New York answered with a 26-yard field goal from Tynes.  Dallas tried to rally as Kitna hooked up with Bryant again on a 15-yard touchdown pass. With the loss, the Cowboys fell to 1-5. Tony Romo (5/7 for 39 yards, TD) left the game in the second quarter with a broken left clavicle.
answer:
How many games had the Cowboys won in the season by Week 7?
