There are five classes class 1, class 2, class 3, class 4 and class 5 in a school. They are one above the other. Class 1 is at the bottom, then class 2 above it and so on. Five videos M1, M2, M3, M4 and M5 are displayed in these given classes. Only one video is displayed in a particular class. Each video is displayed only one time. Video M5 is displayed at an even numbered class. Video M2 is displayed at class 1. Video M1 is displayed at the class just below M5. Video M4 is not displayed at even numbered class. Which of the following statement is not correct?
Which of the following statements regarding static methods are correct?
1. Static methods are difficult to maintain, because you can not change their implementation.
2. Static methods can be called using an object reference to an object of the class in which this method is defined.
3. Static methods are always public, because they are defined at class-level.
4. Static methods do not have direct access to non-static methods which are defined inside the same class.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Straight As may be the wrong goal, suggests a new study that has determined learning is optimized when we fail 15% of the time. P. This is a concept that society has intuited for a long time, across a variety of domains — for instance, this just-outside-one’s-grasp learning is observable in video games, in which the player is encouraged or forced to a higher level of difficulty once a performance criterion has been achieved.  Q. In both cases, machines and animals learned the fastest when difficulty was such that the subject would be right 85% of the time and be wrong 15%. But researchers say their finding is likely applicable to humans.  R. Interestingly, it’s not a new concept — the “zone of proximal development,” a theory developed in the 1930s by psychologist Lev Vygotsky described the sweet spot of learning: when a student is faced with a challenge just beyond their ability to solve it alone. It’s a ‘Goldilock’s zone'. S. A ratio, developed by researchers at various universities was tested on computers via machine learning and applied to previous research looking into how animals learn.  6. If one is taking classes that are too easy and acing them all the time, then one probably isn’t getting as much out of a class as someone who’s struggling but managing to keep up.
