It's biased. Grumpy people have a right to have their opinions known just as well as cheerful people. Grumpy looks are momentary. They can be brought about (especially at a University) by math problems that are illusive, by girl friends (or boy friends), that are illusive, by something for lunch that was barely edible, by any number of things. 

She should ask people on some sort of other scale that is more random.

Answer:

B) the same amount of capital and labor

Explanation:

Only an increase in productivity shifts the production function upward given that all factors of production remain the same. Generally technology improves productivity and causes those shifts.  

Productivity measures the rate of output per unit of input. E.g. I write 10 pages per hour. If my writing productivity increases, I will write 12 pages per hour. Labor productivity is measured by the amount of output produced per hour worked.

Hello there!

Let's take note of some things first. When a argument occurs, there's always two different kind of people. You would have someone who think he has a point and he explains his opinion on this matter, and then you would have the other opponent who would most likely say the complete opposite of this other person.

Now, when conduction the argument of the topic "cell phones", there would be a ton of different opinions on this matter.

For an example:

(Person #1) - opposer.

Cell Phone's are very useful, when you need to call a person, you would have something to communicate with the other person. It would be encounter as a essential in our every day life.

 (Person #2) - opposer.

I believe that Cell Phones are unsafe. People could track you down and hurt you to the full. They can take your information, and then you would have some several bad cases on this matter. I believe that Cell Phones are not safe.
                                            __________
Based on looking at this example here, you would see on how they're are two different opinions here. They both have different explanations.

I hope this helps you!
