Article: The Strumica Carnival (Macedonian: Струмички Карневал, translated Strumichki Karneval) has been held since at least 1670, when the Turkish author Evlija Chelebija wrote while staying there, "I came into a town located in the foothills of a high hillock and what I saw that night was masked people running house–to–house, with laughter, scream and song." The Carnival took an organized form in 1991; in 1994, Strumica became a member of FECC and in 1998 hosted the XVIII International Congress of Carnival Cities. The Strumica Carnival opens on a Saturday night at a masked ball where the Prince and Princess are chosen; the main Carnival night is on Tuesday, when masked participants (including groups from abroad) compete in various subjects. As of 2000, the Festival of Caricatures and Aphorisms has been held as part of Strumica's Carnival celebrations.

Question: Who ran from house to house, laughing, screaming, and singing?
Ans: masked people


Article: Epigenetics is the study of mitotically and/or meiotically heritable changes in gene function that cannot be explained by changes in the underlying DNA sequence but cause the organism's genes to behave (or "express themselves") differently. One example of epigenetic change is the marking of the genes by DNA methylation which determines whether they will be expressed or not. Gene expression can also be controlled by repressor proteins that attach to silencer regions of the DNA and prevent that region of the DNA code from being expressed. Epigenetic marks may be added or removed from the DNA during programmed stages of development of the plant, and are responsible, for example, for the differences between anthers, petals and normal leaves, despite the fact that they all have the same underlying genetic code. Epigenetic changes may be temporary or may remain through successive cell divisions for the remainder of the cell's life. Some epigenetic changes have been shown to be heritable, while others are reset in the germ cells.

Question: When DNA has different markers, how it that presented in plants?
Ans: prevent that region of the DNA code
