Who developed the Benkelman beam deflection studies (BBD) and in which year? Correct Answer A.C Benkelman in 1953

It was A.C Benkelman who devised the Benkelman beam deflection studies in the year 1953. It was during the AASHO (now AASHTO) road test for the purpose of measuring the deflection of the pavement layers.

A,B,C,D,E,G and I are seven friends who study in three different standards namely 5th, 6th and 7th such that not less than two friends study in the same standard. Each friend also has a different favorite subject namely History, Civics, English, Bangla, Science , Maths , and Economics but not necessarily in the same order. A likes Maths and studies in the 5th standard with only one other friend who likes Bangla. I studies with tow other friends . Both the friends who study with I like languages (Here languages include only Science , English and Bangla ) . D studies in the 6th standard with only one person and does not like Civics . E studies with only one friend . The one who likes history does not study in 5th or 6th standard . E does not like languages. C does not like English , Science or Civics. Which combination represents E's favorite subject and the standard in which he studies?
