I can't give you a specific answer, but in general the testator appears to be directing the executor to make certain charitable gifts, without specifiying particular charities. Instead he or she is giving guidelines for picking those charities. If the directions in a will are clear and unambiguous, then the executor has a duty to follow the terms of the will, but if the will is unclear, the executor can petition the court for instructions regarding the gift of gifts mentioned.
I recommend consulting an attorney to determine the best steps to take.

The language that you have typed seems easy to understand. It provides for a charitable gift. The organizations are identified by class, not by name. The executor should retain a lawyer to help the executor determine both the amount of the charitable bequest and the appropriate charities to benefit from that bequest. If the lawyer is uncertain, the lawyer will petition the Probate Court for an interpretation.
Of course if you typed the entire provision we could give you a specific interpretation. However, this is something for which you should not be consulting a lawyer over the internet. You need to walk into a competent lawyer's office in San Francisco and buy an hour of time to get a useful response.
I see well drafted wills and badly drafted wills in my practice. This one is pretty badly drafted because it leaves so many loose ends and leaves so much discretion to the executor. Fortunately, the beneficiaries are all charities. if the benficiaries were individuals there would most likely be a will contest. Charities are less likely to spend money fighting over bequests unless milions are involved. See a probate lawyer.
