From the given paragraph, the two correct conclusions that can be drawn are:

1. Companies use a variety of advertisement strategies to promote business.
Justification: The paragraph mentions that people encounter many kinds of advertising in everyday life, including printed advertisements, poster ads, neon signs, billboards, and commercials on TV and radio. This indicates that companies employ different strategies to promote their business.

2. Effective advertising is an important activity for most successful companies.
Justification: The paragraph states that the purpose of most advertising is to sell products or services and that large business firms use advertising to create a favorable image of their company. This implies that successful companies recognize the importance of effective advertising in promoting their products or services and improving their overall reputation.

The other statements can be ruled out:

- TV and radio advertisements are the most effective ways to advertise business: The paragraph mentions various other forms of advertising, such as printed ads, poster ads, neon signs, and billboards, indicating that TV and radio ads are not the only effective ways to advertise.
- Without good advertising, it is unlikely that you will have a successful company: While the paragraph emphasizes the importance of advertising, it does not explicitly state that a company cannot be successful without advertising.
- Printed advertisements are the most effective strategies to promote business: The paragraph mentions different types of advertisements, suggesting that printed ads are not the only effective strategy.

The evidence that best supports Alejandro's claim that corporate advertising in public schools would be an unfair practice is option B: "A study conducted by a mass communication journal shows that children lack the experience and knowledge to evaluate the purpose of the persuasive advertising appeals, making students particularly vulnerable targets."

Let's break it down step by step:

1. Option A states, "Statistics show that children aged 13–19 view advertisements more than any other age group, which means that their purchasing power will increase if they are exposed to more advertisements while attending school." While this statement provides information about the exposure and influence of advertisements on children, it does not directly address the question of unfairness. The focus is on the increase in purchasing power, which may not necessarily relate to the unfairness of corporate advertising in schools.

2. Option C states, "Most school-aged children are unable to buy the products that would be advertised in their schools; therefore, using such ads would distract students from their school work by shifting their focus to consumer products." This option highlights the potential distractions caused by advertising in schools, but it does not directly address the unfairness of the practice. The inability to buy the products being advertised is mentioned but does not provide substantial evidence of unfairness.

3. Option D states, "Students are more likely to buy and use products and services from the advertisement that is most appealing to them; if they are exposed to these at their school, they will not buy anything they see outside the school." Although this statement acknowledges the influence of advertising on student behavior, it does not address the unfairness of corporate advertising in schools. It mainly focuses on the impact of exposure to advertisements and students' preferences.

4. Option B, on the other hand, states, "A study conducted by a mass communication journal shows that children lack the experience and knowledge to evaluate the purpose of the persuasive advertising appeals, making students particularly vulnerable targets." This option provides the most relevant evidence to support Alejandro's claim of unfairness. The study mentioned suggests that children lack the necessary skills to critically analyze and understand the persuasive intentions behind advertising appeals. This vulnerability makes them unfair targets for corporate advertising within public schools.

In summary, option B is the best evidence as it directly addresses the unfairness of corporate advertising by highlighting the vulnerability of students due to their limited ability to evaluate persuasive advertising appeals.

This question has many subsections, the answers to the questions are below

Explanation:

Independent variable (IV) is the variable that is changed or manipulated by the experimenter while the dependent variable (DV) is the variable that is being measured in an experiment. The control variable (CV) is the variable that is kept constant throughout the experiment. The DV, IV, and CV for the following experiment are:

Independent variable (IV) is the variable that is changed or manipulated by the experimenter while the dependent variable (DV) is the variable that is being measured in an experiment. The control variable (CV) is the variable that is kept constant throughout the experiment. The DV, IV, and CV for the following experiment are:

1. What amount of sunlight makes pea plants grow tallest?

IV: Amount of sunlight

DV: Height of pea plant

CV: Same pea plant, Water

2. Which type of soda has more sugar: Brand X, Brand Y, or Brand Z?

IV: Type of Soda

DV: Sugar content

CV: Same volume of soda

3. Is the height of a ball’s bounce affected by the height from which the ball is dropped?

IV: Height from which ball is dropped

DV: Height of ball's bounce

CV: Same weight of ball, same size of ball

4. Which battery will last the longest: Superlast or Energy Star?

IV: Type of battery

DV: longevity of battery

CV: Same usage period

5. Is the water temperature of Lake Michigan affected by the depth of water?

IV: Depth of water

DV: Water temperature

CV: Same lake

The factors that are kept the same in an experiment is the CONTROL VARIABLE

The is also known as the responding variable- DEPENDENT VARIABLE

This is the one thing that is changed by the experimenter- INDEPENDENT VARIABLE

This is also called the manipulated variable- INDEPENDENT VARIABLE

1) IV: The quantity of salt added

DV: The resultant density of the salinated water

Hypothesis: The egg will float when the  mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg

2) IV: The extension of the rubber band above original length in centimetres

DV: The distance flown by the rubber band

Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown

3) IV: The wing span of a paper airplane

DV: The distance flown by the plane

Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance

4) IV: Presence of more light

DV: Height to which plant grows

Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow

5) IV: Amount of vinegar in the canister

DV: The height a rocket will launch

Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced

6: IV: Surface area of the coin

DV: The number of drops held

Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops

7. IV: Number of hours of study

DV: Science score

Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done  related to the science topics
