What is the difference between la fecha and momento especifico

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

Select the best translation for the following term or phrase. what did i do? ¿qué es eso? ¿qué puedo hacer? ¿qué quiere decir ? ¿qué hice?

Which of the following would fit these sentences? 1. es importante comer de grupos de comidas cada dia2. estoy (with you); los guisantes son saludables3. en una ensalada tomates no hay muchas grasasword bank: 1. la salud, 2. bien, 3. lechuga, 4. comida, 5. que si, 6. todas, 7. prefieres, 8. de acuerdo
