Evolution is the change in allele frequency over time in a population of organisms.
Alleles are different molecular forms of the same gene and when their frequency changes in a population it indicates " hard " inheritance has taken place; the only type of inheritance that leads to evolution. Building bigger muscles during you lifetime can not pass the bigger muscles on to your progeny, thus mo evolution in any population.

Why was Lamarck's theory of evolution not eccepted?
Not well supported by the evidence and basically just assertion. Lamarck asserted that acquired characteristics, such as muscles developed during one's lifetime, were heritable. They are not. He also asserted that an organism had a " desire " to evolve. This was also not true.

What role did Lamarck think acquired characteristics played in evolution?
Lamarck put two ideas into his theory of evolution thought to be true in his time. 1. Use and disuse - people lose characteristics they don't use and keep the other ones . 2. Individuals inherit the traits of their ancestors. So instead of the environment selecting traits, he said that the species selected the traits.
Which of Lamarck's ideas turned out to be true Which turned out to be false?
Right: adaptions to environment wrong: acquired traits are passed on
A change in gene frequency in a population over time is a foundation of biological evolution true or false?
True. That is the definition of evolution.
If genetic mutation almost always leads to sterilization and death then how can evolution be true?
Genetic mutation does not always lead to sterilization as you point out. This however is not the way evolution happens. Evolution occurs mainly through small adaptive changes over a long period of time that are not mutations. Evolution does not happen suddenly.
