Answer 1

42. 10-1km (intended: 10–1 m for VHF)
43. ≤54Mbps
44. 2.4GHz
45. 5-15 Km
46. All of the above
47. All of the above
48. Three
49. Two
50. All of the above
51. WI-FI Protected Access
52. 2.4GHz
53. ≤100 Km (intended: ≤100 m)
54. TKIP/MIC
55. Both a and b
56. 100-10m
57. 2.4GHz
58. Wired Equivalent Privacy
59. ≤100 Km (intended: ≤100 m)

Note: Several choices appear to have unit typos (Km vs m). I selected the options that match the standard wavelength/range values.
