According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A  (through these points by the shortest distance), he has to follow a path point A → B → F → E.

Thus travelling from point A, he will pass the first point B.

Hence, the correct answer is "Point B".

Answer:
The value displayed if the formula "= "$55.00" 5" is entered into a cell is 60 (Option B).
Here is the detailed solution:
1. The formula "= "$55.00" 5" combines a text string "$55.00" with the number 5.
2. When a text string is combined with a number using the plus sign (+) operator, Excel tries to convert the text into a number.
3. In this case, "$55.00" cannot be converted into a number because it contains a dollar sign and double quotes.
4. As a result, Excel treats "$55.00" as text and concatenates it with the number 5.
5. The result of the formula is the text string "$55.00" followed by the number 5, which is " $55.00 5".
6. Since the resulting value is a text string, it cannot be mathematically calculated.
7. Therefore, the value displayed in the cell will be the text string itself, which is "$55.00 5" (Option C).
8. Option B, which states 60, is incorrect because the formula does not perform any mathematical operations on the text string and number.
9. The correct answer is Option C, which displays the text string "$55.00 5".

Explanation:
An inkjet printer is a type of printer that uses ink to create images or text on paper. Let's analyze each statement to determine the correct answer.
i) prints an entire line at a time:
This statement is incorrect. Inkjet printers do not print an entire line at a time. Instead, they print one small dot at a time, gradually building up the image or text.
ii) is a non-impact printer:
This statement is correct. Inkjet printers are non-impact printers, meaning they do not physically strike the paper to create the image or text. Instead, they use ink droplets to create the desired output.
iii) allows multiple copies to be taken at a time:
This statement is incorrect. Inkjet printers typically do not have the capability to produce multiple copies at a time. Instead, they are designed for single-sheet printing, and if multiple copies are required, the user would need to manually feed each sheet.
iv) prints one character at a time:
This statement is incorrect. As mentioned earlier, inkjet printers print one small dot at a time, not one character at a time.
Conclusion:
Based on the analysis, the correct answer is option A: i and ii. An inkjet printer prints one dot at a time and is a non-impact printer.

While introducing every concept to the students and important activities should be done to make students interesting and curious about the concept. The concept should be started in such a way that as it progresses further the students should be more involved to construct knowledge.
Key Points
Asking students to vote on which of the four given organs is most important and asking them to explain why would be the best hook activity to introduce the heart as:

• The heart is the most important organ of our body which pumps the blood to hold the body and runs the total circulatory system.
• The students would be given organs like kidneys, heart, liver, and pancreas.
• The students will be individually asked to select one of the organs from the four which they consider to be the most important organs of our body.
• Then each student will be asked to explain the reasons why he or she considers that particular organ to be the more important organ of our body than the other three.
• As the discussion progresses the important functions of the heart will be familiarized to the students and they automatically know the importance of the heart and are so interested to know more about it.

Hence asking students to vote on which of the four given organs is most important and asking them to explain why would be the best hook activity to introduce about heart.
Additional Information

• On the other hand asking the students to draw the shape of the heart, giving them chance to choose if they want to learn about the heart or kidney first, and showing students a movie clip with the heart rate on the monitor or not best hook activities to introduce the topic because in this the curiosity of students and knowledge construction will be less.

• There are different kinds of thinking styles which include creative, logical, concrete thinking, etc. Creative thinking aims at novelty in the first instance rather than truth.
• It necessarily has to be different from the conventional modes of thinking. It is labeled in psychology as divergent thinking which refers to a way of solving problems by more than one approach.

Key Points

Some of the ways to promote creative thinking are:

• Asking students to raise questions instead of requiring them to answer questions teachers pose
• Asking students to observe the everyday world around them and raise questions about it
• Asking them to identify suitable problems. where they can apply their knowledge
• Adopting the discovery model of teaching wherever this is possible, offering successive clues to the answer to orient them to lateral thinking

Hence, it could be concluded that asking students to observe the everyday world around them and raise questions about it should be followed by teacher to foster creative thinking.

Hint

• Lateral thinking: Edward de Bono who originated the concept of lateral thinking says that it is made of a set of specific techniques that promote creative problem-solving. It is the generation of alternative ways of looking at the same phenomenon or problem.
