8. **B. and**<br /><br />Snow White is described as possessing two qualities: beautiful and kind. "And" is the conjunction that correctly connects these two positive attributes.<br /><br />9. **D. swam**<br /><br />The sentence describes past actions. "Explored" is past tense, so the verb describing swimming must also be in the past tense. "Swam" is the past tense of "swim."<br /><br />10. **B. writing - sending**<br /><br />The sentence describes a habitual action using the present continuous ("I practise"). The gerunds "writing" and "sending" are needed to function as the objects of the verbs "practise" and "by". The structure is "practise [gerund] by [gerund]".<br />
