Mapping out the family age order
I'm arranging 小红's family by age: two older sisters, 小红, and four younger sisters. The aim is to figure out 小青's older sibling count, considering the birth sequence and not the siblings themselves.
Pinpointing 小青's age status
I’m working through the phrase "第三小" to figure out if 小青 is the third youngest or the second oldest among the four younger sisters.
Pinpointing 小青's position
OK, let's see. Interpreting "第三小" within a group of four, it refers to the third from the youngest when ordered from youngest to oldest, tagging 小青 as the third youngest.
Identifying 小青's age
Mapping out the family dynamics, I conclude that 小青 is the second youngest of 小红's four younger sisters, directly confirming that she is the third youngest overall.
Determining the youngest
Listing the four younger sisters from youngest to oldest reveals that the third youngest is M2, suggesting 小青 as the second oldest among them.
Pinpointing 小青's spot
Interestingly, 小青 fits between 小红 and the four younger sisters, specifically in the second oldest position. Each sister's age and rank provide a clearer family timeline.
Counting 小青's older sisters
OK, let me see. 小青 has four older sisters: 从 S1 到 S2，到 小红和 M1. They form a distinct group based on familial relationships and gender.
