6. What instrument do you play? Talk about your favorite
instrument.
A flute can be described as a woodwind instrument, generally of a tubular shape, that is played by blowing across a specially-shaped opening (known as the embouchure) in such a way as to produce a vibrating column of air whose pulsations we hear as sound.
7. Talk about the string section of instruments
The strings are the biggest section, although there are only four kinds of instruments: violin, viola, cello, and double bass.  An orchestra consisting solely of a string section is called a string orchestra. Smaller string sections are sometimes used in jazz, pop, and rock music and in the pit orchestras of musical theatre.
8. Talk about the percussion section of instruments.
The percussion section has the largest variety of instruments, but in an orchestra they will have the smallest number of players. The percussion section can include tuned percussion instruments like xylophone, glockenspiel, vibraphone, or marimba. Non-tuned percussion can be other kinds of drum like bass drum, snare drum, side drum, and a variety of others: tambourine, cymbal, castanets, triangle, woodblock, claves to name the most common ones.
9. Talk about the woodwind section of instruments.
The woodwind sit in one or two rows (depending on the size of the orchestra) behind the strings. There are four main woodwind instruments: flute, oboe, clarinet, and bassoon. There are two main types of woodwind instruments: flutes and reed instruments (otherwise called reed pipes).

11. Talk about the national flag of Uzbekistan.
12. Describe the national flag of Uzbekistan.
The flag of Uzbekistan consists of three horizontal azure, white and green bands separated by two thin red fimbriations, with a white crescent moon and twelve white stars at the canton. Adopted in 1991 to replace the flag of the Uzbek Soviet Socialist Republic (SSR), it has been the flag of the Republic of Uzbekistan since the country gained independence in that same year. The design of the present flag was partly inspired by the former one.
