Which of the following factors is NOT relevant in assessing the capacity of the dependent to provide for their own needs?

The capacity of a dependent to provide for their own needs typically hinges on their own personal circumstances and abilities. In assessing factors that impact this capacity, aspects such as the age and health of the dependent play a crucial role; these elements can significantly influence an individual's ability to support themselves. Similarly, the dependent's earning capacity is a direct measure of their financial independence and ability to meet their needs.

The length of cohabitation can also be relevant as it may indicate the level of support and resources available to the dependent through a partner, thus having implications for their capability to provide for themselves.

In contrast, weather conditions during cohabitation do not have any direct relevance to an individual’s ability to provide for their own needs. While weather could affect living conditions, it does not inherently impact a dependent's personal capabilities or resources. Therefore, this choice is unrelated to the dependency assessment in this context.
