Context paragraphs:
Divide and choose: Divide and choose (also Cut and choose or I cut, you choose) is a procedure for envy-free cake-cutting between two partners.  It involves a heterogeneous good or resource ("the cake") and two partners which have different preferences over parts of the cake.  The protocol proceeds as follows: one person ("the cutter") cuts the cake into two pieces; the other person ("the chooser") chooses one of the pieces; the cutter receives the remaining piece.

Connection (dance): In partner dancing, connection is a physical communication method used by a pair of dancers to facilitate synchronized dance movement, in which one dancer (the "lead") directs the movements of the other dancer (the "follower") by means of non-verbal directions conveyed through a physical connection between the dancers.  It is an essential technique in many types of partner dancing and is used extensively in partner dances that feature significant physical contact between the dancers, including the Argentine Tango, Lindy Hop, Balboa, East Coast Swing, West Coast Swing, Salsa, and Modern Jive.

Merenhouse: Meren(gue)house/Merenrap is a hip hop music style formed by blending Dominican merengue music with rap, dancehall reggae and hip hop.  The group Proyecto Uno pioneered the genre.  Merenhouse usually combines a rap style of singing (talk-singing) with actual singing.  It has instruments that are typically in merengue music, such as saxophones, trumpets, accordion, bass, guitar, güira, tambora (drum).  However, they can be combined with electronic sounds or even electronic sounds sampled from the actual instruments (musch like house music).  Sampling music means to take a sample or portion of a sound recording to reuse it in a song.  Merenhouse is very upbeat for dancing, like house music.  It is hard to identify merenhouse based on its time signature and rhythm alone.  Some merenhouse music is in a fast 2/4 beat and has typical merengue style rhythms.  Some also is in a slower 4/4 beat, identifying more with the hip hop style.  Merenhouse can be characterized mostly by the instruments/electronics used and the combination of vocal styles.

Solo dance: A solo dance is danced by an individual dancing alone, as opposed to couples dancing together but independently of others dancing at the same time, if any, and as opposed to groups of people dancing simultaneously in a coordinated manner.  Solo dancers are usually the best dancers in a group or dance school.  Most solo dancers start after about 6–7 years of dance or sooner.  Most soloists are company kids of their dance school.  They are usually in more than one dance.

Venezuelan merengue: Merengue is a musical form extended through all the Caribbean.  The first occurrences of merengue in print in Venezuela are from scores of “dance merengue” of the second half of the 19th century.  As a dance craze, merengue acquired popularity in Caracas during the 1920s.  It is distinct from the vastly more popular Dominican merengue.  Although they share the same name, the rhythms have very little in common, except that they were commonly written for partner dancing.

Partner dance: Partner dances are dances whose basic choreography involves coordinated dancing of two partners, as opposed to individuals dancing alone or individually in a non-coordinated manner, and as opposed to groups of people dancing simultaneously in a coordinated manner.

Sexual racism: Sexual racism is the "sexual rejection of the racial minority, the conscious attempt on the part of the majority to prevent interracial cohabitation."  It is the discrimination between potential sexual or romantic partners on the basis of perceived racial identity.  However, not everyone agrees that this should be classified as racism, some argue that distinguishing among partners on the basis of perceived race is not racism at all but a justifiable personal preference.  The origins of sexual racism can be explained by looking at its history, especially in the USA, where the abolition of slavery and the Reconstruction Era had significant impacts on interracial mixing.  Attitudes towards interracial relationships, and indeed marriage, have increased in positivity in the last 50 years.  In 1968, 73% of US citizens disapproved of the right to marry inter-racially, whereas this figure dropped to 17% by 2007, this illustrating the reduction in discriminatory attitudes towards interracial dating.  Irrespective of this, there still remains the issue of sexual racism in the online dating world, in that preferences appear to follow a racial hierarchy.  The exclusion of races dissimilar to one's own is a main feature of sexual racism, however a reluctance to date inter-racially predominantly spans from the discriminatory views often possessed by those in society, as opposed to purely a same-race individual preference.  Moreover, this racial discrimination also deviates into the form of the sexual dehumanisation of individuals of other racial identities.  Sharing the basic premise, originating from the 'taboo' nature of interracial relations, individuals of other racial groups are classified as forbidden sexual objects; the result of a racial fetish.  This sexualised reductionism is, concurrently, a form of sexual racism.

Alegrías: Alegrías (] ) is a flamenco palo or musical form, which has a rhythm consisting of 12 beats.  It is similar to Soleares.  Its beat emphasis is as follows: 1 2 [3] 4 5 [6] 7 [8] 9 [10] 11 [12].  Alegrías originated in Cádiz.  Alegrías belongs to the group of "palos" called Cantiñas and it is usually played in a lively rhythm (120-170 beats per minute).  The livelier speeds are chosen for dancing, while quieter rhythms are preferred for the song alone.

Group dance: Group dances are danced by groups of people simultaneously, as opposed to individuals dancing alone or individually, and as opposed to couples dancing together but independently of others dancing at the same time, if any.

Dance partnering: Dance partnering is dancing performed by a pair of dancers, typically a male and a female, in which the pair strives to achieve a harmony of coordinated movements so that the audience remains unaware of the mechanics.  It relies on the application of that facilitate coordinated movements by a pair of dancers.  In particular, it usually involves one dancer providing guidance, support, or both, for the other dancer.  Dance partnering technique appears in various forms in many types of dance and is an essential part of all partner dances.
