Final answer:
Proposal 1's lack of effectiveness in fundraising for the library can be attributed to a lack of affordability, attention, and parental support.
Step-by-step explanation:
Proposal 1's lack of effectiveness in fundraising can be attributed to several factors. First, the proposal may suffer from a lack of affordability, as the library may be located in an area where many people cannot afford to contribute. Second, the proposal may not receive enough attention from the community, as some individuals may not prioritize or be aware of the children's fundraising efforts. Lastly, the proposal may lack parental support, as many parents may be too busy with work or other responsibilities to actively participate in community initiatives.
These weaknesses contribute to a lack of sufficient funds being raised before the deadline, which hinders the success of Proposal 1 in bringing more money to the library.
