- B. Animals use coloration to hide from predators.
- C. The scarlet kingsnake and the coral snake have nearly identical markings.
- D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.
Correct Answer: A
Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.

What is the first step to take after planting potatoes?
- A. Mound soil around the base of the plant.
- B. Water immediately.
- C. Mix fertilizer or compost into loosened soil.
- D. Place potatoes 1 foot apart.
Correct Answer: B
Rationale: The correct answer is B: Water immediately. After planting potatoes, the first step should always be to water them immediately. This is crucial to settle the soil around the newly planted potatoes, ensuring good contact between the roots and the soil. Watering helps kickstart the growth process and provides the necessary moisture for the newly planted potatoes to establish themselves successfully. Choices A, C, and D are incorrect because mounding soil, mixing fertilizer/compost, and spacing potatoes should be done before or during planting, not immediately after.
