Answer: Read explanation and think of common sense with weathers and months. Julio(July), Abril(April), Enero(January), Febrero(February), Mario(March), September(September), Octubre(October), Mayo(May).
Explanation: Basically the way I see it, is that it's asking what month belongs to a picture that describes a season/weather/temperature. For example, I would personally say that picture 7 goes with number 7 because winter as seen on the picture would belong to "En diciembre" which means in the month of December.
