answer:We meticulously collected a total of 44 samples of fine-grained mudrock and marls from nine sedimentary sections located across the External Rif sub-domains. These sub-domains consist of Intrarif (Aouzai section), Mesorif (Izzarene, Tabouda, Taineste, and Marticha sections), and Prerif (Outita, Jbel Zerhoun, and Dhar Nsour I and II sections). Our sampling strategy involved choosing representative samples from each section to ensure the accuracy and reliability of the data. The selected samples cover a wide age range, from Domerian to late Oxfordian, thereby providing a comprehensive snapshot of the sedimentary rock formations in the sub-domains. To ensure the accuracy of our findings, each section was meticulously measured and sampled. Consequently, we can confidently assert that our data provides a deep insight into the geological history and composition of the External Rif sub-domains.

answer:We have collected a total of 44 samples from nine sedimentary sections located within the External Rif sub-domains, which consist of Intrarif (Aouzai section), Mesorif (Izzarene, Tabouda, Taineste, and Marticha sections), and Prerif (Outita, Jbel Zerhoun, and Dhar Nsour I and II sections). These samples comprise fine-grained mudrock and marls that are representative of the sedimentary rocks in the sub-domains and range in age from Domerian to late Oxfordian. Our sampling methodology was designed to ensure that we obtained representative samples from each section, thereby ensuring the accuracy and reliability of the data for the purposes of our research. The dataset we have compiled provides a comprehensive snapshot of the geological history and composition of the External Rif sub-domains. To accomplish our research objectives, we carefully measured and sampled each section to ensure that they conform to established scientific standards. As a result of our meticulous efforts, our findings provide deep insights into the sedimentary rock formations of the sub-domains in question.

answer:很抱歉，作为一个AI文本生成器，我无法直接帮您绘制图像。但是，您可以在免费的在线图像编辑器或者使用类似Adobe Photoshop的软件上，将夜景和流星的照片合成在一起。此外，您可以在网上搜索夜景和流星的图片，有许多图片库可以满足您的要求。

answer:如果您打死一只鸟，树上原本有五只鸟，那么现在还剩下四只鸟。但是，鸟可能会因为惊吓而飞走，所以实际上树上可能已经没有鸟了。所以正确答案可能是0只或者4只，具体情况取决于剩下的鸟儿的反应。
