The document discusses several topics including: 1) The plural form in Indonesian does not recognize nominal concord unlike English which adds "s" to make countable nouns plural. 2) Photography communicates some ideas better than words as artists have been drawing pictures since cavemen, and in the 19th century a mechanical way to picture objects as they are was invented. 3) The indefinite article in Indonesian uses "seekor" for animals and "se-" otherwise, as seen in the examples of a dog in the garden and eating an apple.
