Write a Paragraph with New Words

Learn the following English words (remember the meanings and spellings); then without seeing them again, write down a single paragraph containing all of these words (use your brain power to relate them; your paragraph might be funny; no problem; however, it should be correct).

Note that while writing the paragraph you should not look at any word.

Writing the whole paragraph should be done in less than 5 minutes; be fast in writing your own sentences.

Words:
gore: a small usually triangular piece of land (as where two roads diverge)

sorgo: a sorghum cultivated for the sweet juice in its stems (to make sugar and syrup)

pellucid: transparent

coeval: of the same age or antiquity; contemporary

affranchise: to make or set free from obligation or service

eremite: a religious recluse; hermit

gregarious: tending or enjoying to be in crowds and socializing

Numerical Maze P3E2M2 - Medium

In 7 minutes, find a path from the START to the END passing only through numbers that are divisible by 6. Note that there is only one solution for this numerical maze. To make you find numbers divisible by six faster, here is a hint to memorize and apply:

If the sum of the digits of a number is divisible by 3 AND its last digit is even then that number is divisible by 6. For example, 912 is divisible by 6 because the sum of its digits, twelve (9 + 1 + 2 = 12), is divisible by 3 and its last digit, two, is an even number.

Numerical Maze P3E1M1 - Medium

In 8 minutes, find a path from the START to the END passing only through numbers that are divisible by 12. There is only one solution for this numerical maze. To solve this maze faster, first memorize and apply the following three hints:

Hints:

* If a number is divisible by 3 and by 4 then the number is divisible by 12.

* If the sum of the digits of a number is divisible by 3 then the number is divisible by 3. For example, 2130021 is divisible by 3 because 9, the sum of its digits (2 + 1 + 3 + 0 + 0 + 2 + 1 = 9), is divisible by 3.

* If half of a number is an even number then that number is divisible by 4. For example, 72 is divisible by 4 because half of it, 36, is an even number. Also, if the last two digits of a number is divisible by 4 then that number is divisible by 4. As an example: 897232 is divisible by 4 because its last 2 digits; i.e. 32, is divisible by 4.

Chain of Verbs (No. 1) P2E3E3

Before starting this exercise which is as the Chain of Words and the Chain of Names exercises:

1) Take a pen and a few sheets of paper, entitle the first sheet as "Chain of Verbs No. 1".

2) You should accomplish this practice in 40 minutes.

3) Fully concentrated; nobody in the room, no noise and nothing to interrupt you; turn off your cell.

4) You should do this exercise with your maximum speed, in a high speed that you will not be able to do more than that any more; your highest speed.

5) Write down a list of English verbs, starting with Improve. The second verb should start with an "E", because Improve ends with "E". The third verb in the list should start with the last letter of your second verb. Each item in your list should be an English verb containing one or more words. Example: Improve, Eat, Terminate, Execute, End up, Pour, ...

Take a clock/timer to measure time; remember in 40 minutes; without any kind of interruptions.

Your list should be long; the longer the better, so try to write verbs fast as much as possible.

Ready?
