如何做到畫龍點睛
Step 1: Flaws
computerized, commercial, plane’s course
In short of accuracy are three assumptions, respectively: a computerized system would efficiently perform without bugs; commercial airlines might not collide with other non-commercial airliners; and inability to know plane’s course was the main reason for former collisions.
Step 2: Suggestions
a plane, operation, flying conditions; planes, all types
A better investigation is therefore needed, which should carefully explore a plane’s operation and its flying conditions, and thoroughly list all sorts of flying objects that might cause collisions.
Step 3: Flaws + Suggestions
For a final evaluation on this article, in short of accuracy are at least three assumptions, respectively: a computerized system would efficiently perform without bugs; commercial airlines might not collide with other non-commercial airliners; and inability to know plane’s course was the main reason for former collisions. Given insufficient data to solidify these and other hypotheses, a better investigation is therefore needed, which should carefully explore a plane’s operation and its flying conditions, and thoroughly list all sorts of flying objects that might cause collisions.
