Two types of grammatical errors that nonnative speakers of English tend to make are:
- Substitution of a simple form of a verb for all tenses
English can be hard to learn as a second language, specially when it comes to learning irregular verb forms for all tenses. For example, the verb <em>drink</em> changes in all tenses: <em>drank</em> (past simple) and<em> drunk</em> (past participle).
As a consequence, nonnative speakers tend to use the simplest form of the verb, as in: <em><u>Yesterday</u></em><em> I </em><em><u>drink</u></em><em> orange juice for breakfast*. </em>Here, drink was used instead of drank, which is the correct form of the verb for the past simple tense.
      2. Omision of an article
Since virtually every rule for the use of articles in English has many exceptions or subrules, and  the interactions that occur when two or more rules apply can be very difficult to  predict, nonnative also tend to omit articles <em>a/an</em> or <em>the</em> as in <em>I threw ball*</em> . Here, for instance, it is important to learn about countability, that is, if the noun phrase following the article is countable or not. <u>Ball</u> is the noun phrase in the given example and it is strongly countable in this context. Therefore, the correct use would be <em>I threw the ball.</em>
- Regarding the use of ain't in place of other contracted forms when speaking English as a second language, it is a less common grammatical error since it is <u>informal</u> English.
- While substitution of one part of speech for another can occur, this is not the most common grammatical error made by nonnative English speakers.

Answer:
The most logical conclusion one can draw from the information is, Williams’s patient was concerned and troubled.
Explanation:
Daniel Hale Williams was a well known American surgeon who is also known for his first successful pericardial surgery. 
The author writes that, ‘Williams “reassured the patient with his calm, dignified manner.’ Reassuring some means to say things which removes the doubts of a person. And Williams reassured his patient very calmly. And this was done because William’s patient was concerned and troubled about his health, because of which William have given him the reassurance that everything will be just fine.
