What is the text structure of the following paragraph?   the chief and immediate cause of the civil war was slavery. southern states, including the 11 states that formed the confederacy, depended on slavery to support their economy. southerners used slave labor to produce crops, especially cotton. although slavery was illegal in the northern states, only a small proportion of northerners actively opposed it. the main debate between the north and the south on the eve of the war was whether slavery should be permitted in the western territories recently acquired during the mexican war (1846-1848), including new mexico, part of california, and utah. opponents of slavery were concerned about its expansion, in part because they did not want to compete against slave labor. a. narrative b. expository c. descriptive d. persuasive

Era o zi ploioasa. eram la scoala iar un om impartea bilete pentru un circ, bineinteles ca am luat si eu unul. pe bilet scria ca circul va avea loc chiar maine la ora 15: 00, iar intrarea costa 15 lei. eram nerabdatoare sa merg.a doua zi am ajuns, mi-am platit biletul, mi-am luat o vata de zahar si am luat loc sa asist spectacolul. totul se desfasura frumos, claunii dansau, era totul amuzant. se intamplase ca, un sarpe sa scape din cusca sa, si sa vina spre public, ce a urmat mai departe a fost intradevar comic. toti oamenii s-au speriat si s-au urcat pe scaune, urland cat ii tineau plamanii, dar sarpele venise doar sa ia o bucata de popcorn de jos sa o manance, iar apoi a inceput sa faca scamatorii. a fost totul atat de amuzant, deoarece oamenii erau speriati iar sarpele  nu avea nici o vina.spectacolul s-a terminat iar eu am mers acasa si le-am povestit parintilor mei, care si ei la randul lor, au ras cu pofta.
