You will be given a definition of a task first, then some input of the task.
This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Passage: In a game that saw the return of Alex Smith to the Bay Area, the Niners prevailed in a see-saw game, 22-17, on the strength of five Phil Dawson field goals. Kansas City took an early lead on a Smith to Travis Kelce touchdown pass, but Colin Kaepernick hit Stevie Johnson with a TD pass just before halftime for a 13-10 lead. Smith struck again in the third quarter with a 17-yard scoring pass to De'Anthony Thomas, but Dawson hit three more field goals to give the Niners the win. The Niners outgained the Chiefs 357-264, and had a 36:04-23:56 time of possession advantage, but they only scored one touchdown in four trips into the red zone, continuing their season-long problem in that area.
Question: How many times did the Niners go to the red zone and not score a touchdown?
Output:
number
