priority will be given in such project or program to the furnishing of such services to persons from low-income families; and

A grant may be made or a contract entered into under section 300 or 300a–3 of this title only upon assurances satisfactory to the Secretary that informational or educational materials developed or made available under the grant or contract will be suitable for the purposes of this subchapter and for the population or community to which they are to be made available, taking into account the educational and cultural background of the individuals to whom such materials are addressed and the standards of such population or community with respect to such materials.

In the case of any grant or contract under section 300 of this title, such assurances shall provide for the review and approval of the suitability of such materials, prior to their distribution, by an advisory committee established by the grantee or contractor in accordance with the Secretary’s regulations. Such a committee shall include individuals broadly representative of the population or community to which the materials are to be made available.
