E) are comparatively short 
 
266- It is pointed out in the passage that, to meet the needs of the roadways, bridge 
designers --------.
A) were equally involved in the building of new motorways 
B) followed Robert Maillart technique and concentrated on highway bridges 
C) designed highway roads the same as railway bridges 
D) made some of the most spectacular bridges of the modern era 
E) began to use a new building material known as reinforced concrete 
267- We infer from the passage that there was a great demand for highway bridges in 
the 20th century -------- .
F) because more and more cars came into use 
G) as so many railway bridges were turned into highway bridges 
H) although the designing and building of them was uninteresting work 
Ğ) though railway bridges continued to attract the best designers 
J) but engineers found they could not produce enough bridges 
Aeroplane landing-wheel brakes are fitted to all sizes of aircraft for motion after 
landing, for steering during taxing by differential control of port and starboard 
brakes, and to keep the aircraft stationary as the engine is warmed-up or tested. 
Small aeroplanes have simple two-shoe internal expanding brakes manually operated 
and very similar to the standard road-vehicle brake but the larger planes require 
power-operated brakes using compressed air or hydraulic pressure from compressors 
or pumps driven by the inline. Landing-wheel brakes have to be as light and compact 
as possible and they must remain effective and balanced during very high rates of 
energy dissipation due to the great weight of the aeroplane and the very high landing 
speeds. 
 
 268- It is pointed out in the passage that one of the functions of aeroplane's landing-
