Final answer:
The question addresses a legal issue regarding property bequests. A's children B and C have vested interests in the property since they have both surpassed the age condition provided in the bequest.
Step-by-step explanation:
The question pertains to a legal principle regarding property bequests and vested interests. According to the phrasing, if a property is bequeathed 'To A for life, then to such of A's children as live to attain the age of 30,' and considering that A is alive and has two children, B and C, who are both over the age of 30, both B and C have vested interests in the property upon A's death.
This is because they have both satisfied the contingent condition of living to attain the age of 30. Thus, B and C would be entitled to the property after A's life interest terminates.
The subject of this question is Mathematics. The question is asking about the number of generations that have passed since the year 0 AD, given that a generation is about one-third of a lifetime.
To determine the number of generations, we first need to calculate the average length of a lifetime. If we assume a lifetime of 70 years, then a generation would be about 23.3 years.
Since the year 0 AD to the present year is approximately 2,021 years, we can divide this time period by the length of a generation to find the number of generations: 2021 / 23.3 = approximately 86.85 generations.
