Item 7 Read the excerpt from “Choose a Sunscreen Right for Reefs.”

Why should you choose to wear reef-safe sunscreen? First, because reef-safe sunscreen does not contain two chemicals: oxybenzone and octinoxate. In many sunscreens, these chemicals help to filter out or block the sun’s harmful ultraviolet (UV) rays. However, when they wash off in the ocean, they can be carried by the water to nearby coral reefs. Once there, these chemicals can damage the coral polyps. They can make it so the polyps cannot reproduce. They can also kill the algae on the reef. That then triggers a chain reaction. The polyps die, and animals such as parrot fish, which feed on the polyps, have nothing to eat. So they die, as well. Then those fish that eat parrot fish are robbed of their food, too. And once the food chain is broken in this way, it can spell disaster for the reef as a whole.

Question 1
Part A

Based on the information in the excerpt, what is the author’s point?

Reef-safe and regular sunscreens contain similar ingredients.

The chemicals in sunscreen are effective for protecting human skin from the sun’s rays.

By hurting coral polyps, the ingredients in regular sunscreen affect all species in the reef.

When sunscreen is released into the ocean, it spreads very quickly through water.
Question 2
Part B

Which evidence from the excerpt best supports the author’s point?

“In many sunscreens, these chemicals help to filter out or block the sun’s harmful ultraviolet (UV) rays.”

“That then triggers a chain reaction.”

“First, because reef-safe sunscreen does not contain two chemicals: oxybenzone and octinoxate.”

“Why should you choose to wear reef-safe sunscreen?"

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.

answer: inference

explanation:

an inference can be understood as a conclusion to which a person is able to get based on reasoning. it is the same as a deduction, a guess, an assumption.   in the sentence presented, the conjunction "but" gives the readers an idea of contrast, and, therefore, allows them to induce that despite the opponent's characteristics, andrea had something different that made her win.
