ok now it let me respond
1. Tu sabes el precio del vestido?
This sentence means - Do you know what the price of this dress is? Both saber and conocer are translated the same into English (=to know), but saber is to know with the meaning of actual knowledge (I know math well), whereas conocer means that you know someone or someone's work (I know Maria well).
2. Usted conoce a mi hermana Maria, no?
Here you have to use conoce because the question is asking - Do you know my sister Maria? Just apply the appropriate suffix for usted (third person singular), and there you will have your correct answer.
3. Nosotros sabemos hacer windsurf.
This sentence means - We know how to windsurf. Obviously you would use the verb 'saber' here because you want to show that you have the knowledge of doing something, not that you know a particular person.
4. Yo se donde esta la corbata azul.
This sentence means - I know where the blue tie is. Naturally, you would use the verb 'saber' here as well to denote that you know the location of that particular thing you are looking for, rather than a person or their work.
5. Ellas conocen los libros de Carlos Fuentes?
The sentence means - Do they know novels by Carlos Fuentes? Here, you would use the verb 'conocer' meaning that they are familiar with this author's works, rather than 'saber' which wouldn't mean anything in this context.

Tenemos que conservar agua aunque haya¹ suficiente agua ahora. Cuando desaparecen² los bosques, se pierden muchas especies. La gente se preocupará por el calentamiento de la tierra cuando sea³ demasiado tarde. Los carros seguirán contaminando hasta que nosotros encontremos⁴ mejores combustibles alternativos Las especies en peligro de extinción comenzarán a recuperarse tan pronto como nosotros hagamos⁵ algo para protegerlas. Los recursos naturales se agotarán a menos que todas las personas del planeta los conservemos⁶.
Translation: <em>We have to conserve water even though there is enough water now. When forests disappear, many species are lost. People will worry about the warming of the earth when it is too late. The cars will continue to pollute until we find better alternative fuels. Endangered species will begin to recover as soon as we do something to protect them. Natural resources will be exhausted unless all the people of the planet conserve them.</em>
